When I took an applique class from her several years go we used Rinsaway. The product on her website is 5 yards so that is less than $4.00 yard which is kinda the norm. If you look at joann.com they carry Rinsaway for $4.49/yard but it is 45" wide. I have some and like it. Actually I forgot I had it. Need to get it out! Her method is sewing the applique piece to her product right sides together then turning it right side out. I dont know if she uses this for machine embroidery applique but I doubt it. I think it is only for machine applique. Eleanor Burns also uses this method using regular fusible interfacing.
