PASSION FLOWER: 1


My next entry in the origami flowers section is the development of a flower which I shall call the Passion Flower because of the emphasis on radiating stamens. This grew out of the Fragrant Flower of earlier postings.

I began experimenting with the fawn and green example. It has eight petals with alternating colors. Some of the most beautiful of Passion Flowers have alternating petals.

The model was folded while I a finger of my left hand in a splint so it is a little sloppy. At the time I was more concerned with the question of whether the idea was going to work than I was with how well I was folding the model. It is presented "as is" and I hope no-one will be rude enough to use it as an example of my folding prowess.

Instead of a separate petal connector, each petal is slotted into the side of its neighbor. It changes the look of the flower quite dramatically.


Since the Passion Flower has ten petals I created the pink version.




After this I progressed to the bi-color example which is made from sheets of paper with a different color on each side. There is a very limited range of double color papers in folding weight. How I wish the card weight tone-plus-darker-tone range was available in a text weight paper.


The purple/orange combination seemed to be the best choice at the time but the flower has turned out rather darker than I would have liked.

It is not difficult to fold but it helps to have a good supply of cushioned hair pins to hold the pieces together while folding.

Here is the crease pattern for this flower. This is a Model 1.2 version Crease Pattern so it includes a couple of additional creases that were not part of the pre-creasing process of the purple-orange model shown here. (They were added in a less precise manner late in the folding process.)

These additional creases in the inner petals (the ones that are not mirrored on the other side of the diagonal) help to more sharply define and separate the inner petals from their sheaths. They also help to pull the stamen parts together more firmly. The result is a crisper looking flower.




This flower worked well until I tried to connect it to another one. The first examples fell apart too easily, looked ugly, were excessively complicated or pushed the petals apart in a way which spoiled the overall effect. I finally found a sturdy and good looking connection. It requires a "male" and "female" petal - one on one flower and the other on its adjoining flower.

The connection has one drawback: it cannot be accomplished between the petals of finished flowers. Each connecting petal (every alternate one of the ten) has to be connected to a neighbor before being put together with the rest of the petals in its flower head.

Rather than undoing the completed flowers and refolding them I have decided to make new flowers. This time I will alternate the purple-orange double petals with single petals of a contrasting color. I am waiting for a roll of lilac/white craft paper to coordinate with the slighlty garish color-scheme of my precut paper. By the way, I am using 5-1/2" squares for this model. The flowers end up 4" wide and should make a reasonably sized kusudama when 12 of them are connected. The unattached alternate petals should poke out to fill in the small gap between these 12 petal flowers.

In the next posting I will upload CPs for the male and female connecting petals together with pictures of the kusudama as it is put together.

As usual, I am folding/designing more than one model at a time.

Much to my disgust, I STILL haven't completed the last section of the display quality Tier Box I started waaaaayyy back in these postings.

FRAGRANT FLOWER: 5



I have begun to put Type 2 flowers together to form a kusudama. I have three together so far. The leaf connectors, when pulled out sideways, nicely fill in the gaps between the flowers. (See the center of this photo).

I am starting to wonder, however, how I am going to get the last flowers into position. The connectors, you see, are at the bottom of the petals. This will pose some challenges.

The fall back position may be to leave out the top most flower and use the opening as an entry/exit for string and power cords. I intend to poke LED lights through the central hole in each flower, as I did in the earlier photos of this model (in orange and yellow on that occasion.)

FRAGRANT FLOWER: 3




I am still working on a Fragrant Flower kusudama. In the meantime, here is what happened when I put ten Type One petals together. It looks a little like some of the passion vine flowers I have seen. Or maybe a water lily.

I does not look like it will work in a pentagon kusadama arrangement. I suspect that forcing two petals to become one side will distort the flower unacceptably.

THE FRAGRANT FLOWER: 2



I am still experimenting with the No-Glue Fragrant Flower.

I decided to try a different approach to the stamens so that the leaf connector would not interfere with the slotting of the stamen into the petal. This meant shortening the stamen. This was rather a headache. Here is the CP for my first attempt.



The shortened stamen still interfered with the leaf connector but this proved easy to fix. I simply folded the tip of the diamond shaped cup inside. This left a triangular cup for the petal to sit in. Part of the sides fitted neatly under the edges of the stamen, locking it in place. It helps to use a hair pin to keep the back wall against the back wall of the petal during the construction stage.



My solution to the stamen problem resulted in a piece which poked out further than one of the contour folds on the petal so these folds were deleted.



All the pieces looked good and seemed to work well. It was not until I connected the final piece that I discovered that there was a problem. Here is what I got.



Well, it worked and it looks good, but it's not very practical for use as a kusudama unit because it is too floppy and the petals are too far apart. Nor will it work with a LED in its center. In fact, the center was just too floppy for just about anything. It might work well when used as a decoration around a tall pentagonal cylinder. I may try this idea out sometime in the future. It could turn out to be an elegant vase or just a daffodil facsimile.

So I reorganized my fingers and started again. The final solution to the stamen problem didn't change much in the way of creases, most of which are simply redirected. Folding the last part is, however, a bit of a challenge.

The last piece has to be persuaded to sit over the top of its counterpart in order to form the little cup on top. It is difficult because of the fact that the sections which have been folded over to close off the gap at the back pull this section in the opposite direction until the unit is closed. And the unit cannot be closed entirely until this piece has been eased over the top of them. It requires a little patience. Tweezers help.

Perhaps I will find a more sophisticated way of folding this part after I have struggled with a few more of them.


The result, when it is finally achieved, looks good and functions well.

THE FRAGRANT FLOWER


This post continues the No-glue version of a flower used in traditional Japanese kusudama.


This series began in response to the Fragrant Blossom kusudamas created by the inimitable and talanted Puupuu. Here is a link to the folding instructions for this blue and white version of her Fragrant Blossom flower ball.

http://atelierpuupuu.blogspot.com/2008/06/anniversary.html







The No-Glue Fragrant Blossom has been modified and given connectors which look like leaves and sepals. I have renamed it the Fragrant Flower.

Crease Patterns are provided below.

The center hole is now filled with a light emitting diode (LED) which, being cool, does not burn the paper.




The diamond shaped piece (seen on the outside of the flower) connects to a petal in another flower (extra flower connector). It is wrapped around the petal (see the third photo). Actually, the petal sits inside it.

Continuous connection of these will result in a dodecahedron flower ball (ten flowered kusudama).

The electrical leads are slotted through each flower center. They are then bunched together and slotted through the hole in the center of the top flower. Use a plastic conduit to make it look neater.

If you prefer, you can push the lead-containing conduit through the gaps between the flowers so that the central column of every flower can contain a LED.

The leads become the power source for the lights as well as the "string" to hang up the model. Twist them neatly together after they come out of the conduit. You may like to add a LED inside the flower ball so that the light will shine through the gaps. If you use translucent paper (vellum, glassine or common waxed cooking paper) the light will shine through the petals themselves. The problem with these media is that they are more fragile, more brittle and may crease more easily than standard paper.

An alternative idea is to treat (soak or brush on) normal copy paper with oil or wipe on poly. This will make the model more translucent. I have not tried this idea out yet, so beware that you might ruin your model. Try it out on a flower first. Be aware that once the stuff dries you will lose some flexibility. This may make it difficult to connect this flower to other flowers. Wipe on poly makes the paper a little more brittle. This could be a problem. Oils may need to be renewed.




The pink petal connectors (intra flower connectors) are slotted through the gap between the violet petals and folded around the internal "stamen" (through but over the top of the green extra connector flaps inside the petal) and tucked in the nearest side. Repeat on the other side of the petal with another pink intra connector.

Close the flower petal by tucking the protruding "stamens" into the stamen pocket on the other side. The first one tucks into the medial pocket facing it (the one it is touching), the second tucks into the lateral pocket
of the stamen facing it (on the other side of the one it is touching).

Yes, I know this is confusing when written rather than diagrammed. I intend to diagram this some time (which will probably result in my baldness from all the hair tearing out) but it won't be quick. So this, dear readers, is the interim instruction sheet.

I used to teach Australian Year 12 English at both Vocational and Tertiary Orientation levels (US Junior College AA and BA levels). One of the tasks I used to give them was to provide written instructions for a drawing task in such a way that other members of the class could draw the model just from the instructions. The results on the blackboard were usually hilarious, especially if the person was trying to follow instructions for drawing a set of steps. So I will forgive every one of you who fails to follow my instructions for this flower. I am sure that any of my past students who are reading this will be most amused to see their ex-teacher tying herself in verbal knots trying to explain how to construct a complex 3D model. Hi boys!


When I have completed the full dodecahedron model I will post photos here.

I am also working on a ten petal model where there is less space between the petals. The problem with the connection is that there is no straight forward way to connect ten-sided units together. The solution, I think, will be to treat two petals as a unit and connect them to their partners as if they were a single side. I hope this will work. I guess we will find out shortly.

Here are the crease patterns.
