I remenber these from years ago, have never made them but they apeer to be in style agine, most I saw was real cute, I think they would be a good seller, you just never know till you try, come back and tell us if you make then, would be a quick craft to make.
Happy Crafting

Thanks Oddie. I plan to sew two ribbons together to have a different look on both sides. I don't like the hem on the end but don't know any other wan to do them. I have a show April 28 and will let you know if they sell.
