I guess this is going to have to be a learning experience. I never thought to iron on the wrong side or with another piece of material over top. Unfortunately the yellow is through the piece and it is paper pieces, so I can't just remove the damaged parts and replace them.
I guess I'm just going to have to start over, thankfully the piece is only 12" by 12", so it isn't a bed sized piece, but I still didn't want to have to do it again.
Thanks for the help!
Sara,
I'm sorry this happened to you too, but I'm so glad I'm not alone!
