I’ve been working on this particular temari for a really long time, and I’m excited it’s finally done!
(Yes, I really did bake a cake just to use as a photo prop.)
This started as a challenge from a friend to do a ball based on the Portal video game (hopefully you could tell), with the idea of making the two halves of the ball represent the two halves of the portal. The swirl stitch seemed like the most obvious way to create a portal-y pattern, but really does not lend itself easily to being divided in half.
The solution I eventually landed on was to use a C10 division, which does have lines that continue all the way around the ball, and use the small triangle faces instead of the more usual pentagons. To color-divide the ball, I put one line of blue and orange around the equator, then traced over the scrap thread C10 lines already on the ball with the appropriate color. The scrap thread all got cut off at the end. (If you try this, be sure to tack your scrap thread with your base wrap color and save yourself some time.) The only downside to this color-division technique that I found is that the outlines of the triangles can get a little loose, since they’re not actually held taut by traveling all the way around the ball. Be sure to anchor firmly!
Originally I was going to swirl clockwise on all the blue triangles and counter-clockwise for all the orange ones, but it turns out the triangles are too small to build a satisfactory swirl on their own, so I started over and went with alternating CW/CCW triangles, which make those nice fan shapes. It’s a little more of a fractured look than I was originally thinking of, but using the portals can be kind of disorienting (and someone posted a video of their character trapping herself intentionally inside an infinity-looped portal that was awesomely glitchy), so I figure it still works.
Anyway, this temari was a cool puzzle to figure out. It’s probably the most technical fiddling I’ve ever done with a design, and there were no examples to go off of, so I’m pretty proud of it. (I don’t want to swirl again for a while, though. There are a lot of triangles on this ball.)
