Finally had a chance to give this another go. This one came out much better but still not perfect. I adjusted the pattern on the lower part of the wheel and they fit just about perfect with almost no wrinkles. The top part is still a bit wrinkly, but I think I know how to fix it... Still have enough material to do this 2 more times
I did learn that my sewing machine sucks
in order to make the stitching super tight and snug, I need to use thicker thread, but my sewing machine can barely handle what I'm using already. I'm not going to pony up hundreds for a new machine, so I'll just have to live with the a small gap in the seam
Did this one without the red stripe, I think it looks cleaner. I also used double the foam on the inside this time, she's a fatty!
No idea when I'll have time to try again. The good thing is that this really doesn't take a long time now that I know what to do.
