I watched Eleanor Burns and also clicked on the link for spinning the seams onthe 9 patch. And - I got it!!! I see what is meant by those extra seams. I was able to do this on my block (only had 1 seam flipped wrong)- and it sure makes a big difference!!!! Thanks for the links - I'm very visual, and I hadn't seen those yet - those made sense to me.
I have contemplated pressing my seams open as was suggested. I know Leah Day is also an advocate and says the same – she’s never had an issue. I think I would miss the nesting seams when putting together rows. But I am thinking this might be good to try on a smaller quilt. It might be something that I really like as well. My sewing machine doesn’t really like any bulk. L
