Thank you all so very much! Twinkie, I didn't use a jelly roll. I started with a charm pack, cutting the squares in half. Added in more from my stash, as needed...
For all of you who feel intimidated to try feathers, just give it a try. It may give you more confidence to draw the feathers out with a disappearing ink pen, and then follow your lines. It's not that hard once you get going.
Feathering is great for filling in odd spaces like I had between the block stacks...
