I have had many customers sell baby quilts on Etsy made with my applique blocks. Many people would email me and ask my permission to use my blocks for resale which is fine with me. However I don't know how often they sold one because I don't have time to keep up with all....but as for my own sales I can say that Etsy has really picked up some selling speed in the last 3 months. You just have to be persistent.
