Debbie left a comment on this post, asking where I'd gotten that gadget thing that's taking in the back of my jumper. I wanted to answer you up front here, Debbie, so you'd be sure to see it.
I don't know what it's called, but I got it at Wal Mart in the fabric section. Seems like I found it where the buttons are, maybe even on the same rack. That's where I'd suggest looking first, and if you can't find it there, I'm pretty sure a fabric shop would have one. Good luck! And thanks for stopping by!
