The board went together very easily. I tried to concentrate and go slowly when I sewed the seams so they were as even as I could make them. There are a few unperfectly matched corners, but they will stay. The only tedious part was opening all the seams and ironing.
Now I'm on to the pieces. And I'm a little stuck. I don't want the edges to fray and I want the pieces to be perfectly shaped. If I turn the edge under or sew a back to a front and turn, they pieces will have misshapen bits. I've tested a few and it's impossible given the shapes. For me anyway. So I will try heat bond and adhering directly to the fabric. With this method, I'm worried about how to finish the edges. Won't even a blanket stitch allow for fraying? And a blanket stitch is going to be a bitch on some parts of these pieces if I use my machine. My sister suggested doing what I can on the machine and hand-stitching the other bits. That's a good idea, I think.
Here is what the pieces look like. These are my templates. I need to now find colors I like for the pieces and borders.
