Thank you everyone for your suggestions. I'm going to try doubling the film I already have, but also get some of the more fibrous stuff. Janjanq, your ornaments are beautiful!

Janjanq, I agree your ornaments are beautiful!!!

Janjanq,

The ornaments are pretty.

I normally use double layers of the WSS, some only use the mesh WSS and others use the clear. Most of the time I use the clear but depending on the stitch out, you may need more than one or even two layers of it. I also use a universal embroidery needle most of the time and I slow down my machine. Now when I make FSS objects for the kids to play with I use serger thread, I don't want to waste expensive thread on something that may not last. I then go up to a topstitch size 90 needle. If you catch the rip before it damages the design, you can spray a little emb adhesive on the torn area and add some more WSS to it, I piece alot. A lot of the time if I have big enough pieces of FSS I'll piece that together as my second or 3rd layer. I havent used Isacord so I don't know but my machine plays really well with most threads. So check your needle, slow your machine, add more than one layer unless you are using the mesh WSS then one should be good. Go to embroidery.com and they have a section on emb on different fabrics and it'll tell you which needles to use with which project. RNK distributing also has a workbook on stabilizers and techniques.
