Regarding the definition of "fleece":
Keep in mind that Pellon puts out a "fusible fleece" that looks just like batting (to me) and allows one side to be lightly ironed on (w/o steam) and there is NO shifting or stretching. It is very easy to use and is about 46" across, so it's good for lap robes, but could be "mated" in the usual ways to make a wider batting.
I use it often (always for smaller quilts) because I can adhere the backing and panel-piece the front from top to bottom, quilting as I sew. I use this method a lot when I'm doing quilts for charity, for smaller children, and for lap robes. When I use it for a free form or "landscape" quilt I do the front (in pieces, slightly ironing to keep them in place, pull up, replace, etc) until I have it all the way I want it. Then I tuck under one side of a seam, overlapping it to the one next to it, and sew. When doing it this way I then add the backing and quilt it.
If I have the pieces ready (cut out) I can put together a lap robe (4x6') in one day (so it's really a two day project). That means a lot to me when I'm doing quilts for my grandkids to raffle off so they can go on a trip with their choir or their church group.
There is also (but I've never seen or used it) double sided fusible fleece. I'm looking to get it ASAP.
Hope this is informative... remember the definition of "fleece" may have more than one meaning. Sierra
