Yes, I interfaced just the outside fabric with fusible. Thank you so much for a wonderful tut. The finished project is just adorable. I have 10 more cut out and ready to go. My daughter is 11 and is always going to birthday party's and I will have these ready to go with the gifts. I was so surprised how fast you can put one of these together. I encourage everyone to try this. Such an excellent tut. Thanks again.
