Katamari Ball - Katamari
I will still show you how she made it. ;D
She started off with flexible plumbing pipe. She used math to figure out the circumference of a 5ft diameter circle, and determined how long each piece needed to be.
She made a circle for the top, and one for the bottom. These are what she would tie off the ribs to.
Then we tied them to the bottom ring and taped those in place.
We realized that in order for it to stay it needed support beams. So 3 vertical supports were added.
We noticed that the supports were a bit too long, making it slightly egg shaped. She took off a couple inches from the supports to fix this. You can see the difference between before (left) and after (right) above.
One huge problem that we started to encounter was that the frame wanted to twist. We knew that the only way to really prevent this was that the connections for the ribs needed to be rigid. But, in order to store this, we needed it to be collapsable. (So we couldn't just glue the ribs into place.)
At this point we agreed that with all of the supports that were going in to hold up the frame, this was not going to be wearable as a costume, and would have to just be a large prop. This is when we decided to make the Prince costume.
Then she began to work on the pattern pieces for the cover. She used a roll of tracing paper to help her make the ribs equal distance apart and then traced the shape onto tracing paper.
Then she began to pattern the bumps which required a lot of math.
Using this trapezoid (which is green in the picture below), she drew a C-shape, by drawing the trapezoids with the edges touching. Draw the same number of trapezoids that you divided your original circumferences by. Then smooth out the edges and voila!
Then she sewed the ball cover together.
Elanne of Sweet Boake made all of our paper cranes. ;D
Hooks and eyes were used to attach the cranes to the ball, meaning that they are removable.
Discs of cotton batting were cut out so that the stuffing wasn't lumpy.
Then the bumps were painstakingly hand stitched on.
