I found some more fabulous wool sweaters last night at the thrift shop.
The one on the left has a hole in the shoulder, and the one on the right came already felted, so I have no guilt about my plans to snip it up. Just a lot of books with ideas for felted-wool projects!
And check out the turtleneck on the right-hand sweater... it's a little tight for my head, but I think it would make a great hat for a child.
There was a third sweater in my haul, but on further inspection I discovered it didn't have any holes, wasn't already felted, is insanely soft, and fits me perfectly:
So I'm just going to wear it, to stay warm while working away in my cold sewing room.
