I am making little dog jackets with my small peices of fleese it does not take much to make one for a small dog and they are cute as can be and warm on their little bodys when it is cold out.
Have done Rag Quilts with felt pieces, not sure if it would work with polar fleece, good luck on using up your bits...lots of good advice from the "cutes" below...
I always use iron on tearaway on fleecy fabrics.This was recommended to me by my Janome dealer. It prevents stretching. You will have no problems with hoop marks. Just take the fabric out of the hoop when you have finished embroidering. You should have no problems with washing either.Have you ever embroidered on a windcheater? Well, this is exactly the same.
Do it the way mops described and always if I am worried about it, I'll do a test sample and wash and dry it.;)
There were a few beautiful quilts made of fleece, stitched together on a serger. I've been looking through 50 pages to find them, but must have overlooked. When I embroider fleece I put tear away stabilizer in the hoop and use spray glue to attach the fleece - no hoopmarks that way. Works for me, every time. I wish you success.
Thank you mops, I did see them at one stage & was thinking about them. That's what got me to think about doing something similiar. Thank you for your advice.
