I began with the outermost wedge pieces:
I did my best to make the intersection where the edges of the two fabrics meet happen at exactly the 1/4" seam allowance. Because these are all bias edges, any shifting, fudging or easing is not a good idea. Luck was on my side, because here is the outcome:
This looked complicated, but I gave it a try.
At least this time, the two sides were mirror images of each other. All I had to do was center the background piece onto the wedge. Here is what it looked like from the other side:
The alternate wedge pieces had their own little odd shape:
At last, I had the first 3 sections ready to sew together:
And this is what I have now:
I'm just as curious as anyone else as to how that will turn out. Stay tuned....
