I've used the throws, blankets, fleece and minkee on the backs of quilts and I love it! I spray baste then do some pinning. I haven't had any problems and really like how cuddly they are. My only problem has been the lint but I can live with that.

I have used fleece with no problems, and it saves having to use any backing.

Thanks, everyone! I've used fleece without any problems before (works wonderful on pet quilts). And, minky purchased from LQS's has worked fine for very nice quilts. Today, I bought some 'sale' throws to use for backing....hoping to save some money in the process! I bought 3 different 'textures' of minky-type throws to find out which type will work best. With the price of fabrics so high, I thought this might provide a nice price break for a few projects.
It'll be a experiment. I may find a quilt-as-you-go project is the preferred style for something that is problematic but the backing will be nice and soft!

Would it help to use the spray basting?

Just finished a quilt for my newest granddaughter and used some minky type backing that I purchased at JoAnn's. I also frequently use fleece. Love both. Just be sure to use less tension on the backing, so as not to stretch it. I would think that the purchased throws would work the same. Keep thinking I'll try them.

I like to use pre-washed flannel for the back of my quilts that will be used to cozy up in front of the TV or to cozy up in to read a book.

I haven't but a friend of mine did. She recommended 1/2 inch seams instead of 1/4 and lots and lots of pinning. She loved the end result.

I have been thinking of using one of these cuddly throws for a backing, now with all this help I think I will.

Thanks Mary Jane for saying use 1/2" seams instead of 1/4". I can understand why, but I probably wouldn't have done that if I hadn't read this. Thanks.

Yes, I use fuzzy backings of one kine or another on children's quilts. It is a challange keeping them smooth, more or less. Along with being warm they are nonslip.

I have used fleece on many quilts and have not had a problem. When I have to piece it I use the 1/2 inch seam also. I do pin alot but never had a problem with the back puckering. Never used minki as I heard it is hard to work with.
