Try using colouring pages downloaded from the Internet or even colouring books that you bought for your kids to do paper-piecing. I've done quite a number of paper-piecing for my Disney layouts in my USA travel gallery such as below.
Just use the picture in the colouring page and trace templates for paper-piecing (remember to trace it a bit bigger at the part you want to piece it) Then paste it to colour card stocks and just each piece out.
After piecing them together, chalked it to give a little dimension to it. Sometimes, layouts that tells very little stories can be filled up using paper-piecing technique. I had so much fun doing these pages. It is especially difficult to find paper-piecing templates for Disney characters.
