I'm calling it string cells because it kind of reminds me of a jail cell, with the bars going down the middle. It's possible that I've watched too many Law & Order reruns.
My friend, Julie, pinned this quilt on pinterest earlier, and I thought it would be neat to try and replicate a string version of it. I think I'd need to make my background stripes a little chunkier next time to really pull it off. Another option is to offset the background strips in the block, so that it looks more like this. Similar to yesterday, it's one of those blocks where it's much more dramatic in a quilt full of these blocks, rather than one block by itself.
