I have only appliqued one other thing and it didn't go very well. I mean it was okay, but it was obvious that I was inexperienced. I did these differently, opting for the raw edge applique and a straight stitch to sew it down. It went much better. The curves were still a bear, as is clear by the "J". But they are just bath towels so who really cares! :) Thankfully the other 3 all are straight edged letters. The "M" did not get done since my daughter swiped her towel out of the clean laundry before I could tell her not to. I don't really want to applique on a used towel. Don't know why really,other than it just seems yucky. So I still have one to do.
I am also proud of the fact that the fabric I chose went pretty close to perfect with the shower curtain even though I had to go by memory what color green was in it. Woohoo!
