Lovely afghan!
I started making a Homespun afghan several years ago (yarn was from left over scarves that I crocheted for lots of people at work). Then I found out that Homespun doesn’t wash very well; that’s when I abandoned the idea of finishing the large afghan (I made half of it into a lapghan and gave the other half–in pieces–to the cat, who automatically goes into squishy mode whenever her feet touch it). I had all the squares done, too, and was just adding the connecting border around the squares! Sigh!!
Anyway, perhaps the person who buys it will be able to dry clean it. But you might want to let him or her know this at the time of purchase so it’s not ruined after the first wash.
