Thanks to all of you who gave me your opinions on how I should finish these wall pocket blocks. (previous post here).
In the end, I decided to finish them as a series of four individual wall quilts, or wall pockets. Each has a split hanging sleeve on the back, so whoever purchases them can buy one, two, three, or all four, and hang them in whatever configuration fits their space.
You can see the Etsy listings here. The link will take you to the first listing, but that listing is linked to the other three as well.
