Hi Blackie, I love FSL and I only ever use 2 layers of WSS. I know that some designs I have no trouble at all and others I do, are you talking about the angels from "tavernmaker" I made one of these today and I had to slow my speed down to the lowest, and I still had some cotton breakages. Whether or not this might help, have you cleaned out your bobbin area? Good Luck!!!

Mornin...I found that using prewound bobbins for FSL was the trick 4 me :) Good Luck..it is addicting.

I do a lot of FSL designs. This is what works for me. Use 2 layers of Vilene WWS each going a different directions and pulled tight. Use the smallest hoop for the design. Sew at a slow speed and reduce the top tension to 2.3. (I sew regular designs at 3.0). I use Rayon and Poly 40 wt. thread and prewound bobbins. I hope this helps.

bLACKIE, slow machine down to slowest speed. Use same thread n bobbin u have on top, Use 2 layers of WSS. this should do the trick. *4U

I see you've got a number of answers to which I've nothing to add. I hope it works out for you now. Here's a flower.

Hi Blackie, wondering how you are going with your FSL????

Heard a lot here about slowing down he machine...I had never thought of that and have not had too many problems but I am gin to try it on my next FSL..maybe mine will turn out like Shirlene's...Thanks for the question.

I had trouble with those angels too. It turned out to be they didn't convert right. I started over and converted them in a different software. I didn't have any more trouble after that.
