So here's the finished back for the Cherry Goose project, you can see that I needed quite a bit of the white polka dot -- I just had nothing suitable in stash. The cherry print was from the Walmart $1/yard sale. I have one piece left from that buy in stash (bright fun thin stripes), and a back for another project but otherwise accounted for! The smaller piece of the dot is on inside out. Darn it! I've never had to put in a deliberate mistake in any project I've ever made. I thought I was being careful... but I'm leaving it as is.
The second shot is it folded in quarters before I fold it for storage. The red square is the binding, I'm currently doing the "don't press first" method of binding. Not a solid convert, rather like that nice crisp pressed edge for storage, but it is easier/lazier and my results are just fine so that counts for something.
