i use fleece and minkie alot for backs...a couple things...use a stretch stitch, if possible lessen the pressure the foot puts on the fabric (to help with drag) some machines allow this, others do not...if it's possible it helps. since you are not using a batting you do not have to worry about density of quilting...just enough to hold it together is enough, i recommend a large swooping all over design. or you could just do a few lines down and across...you don't need alot of quilting. after it is quilted then you trim your backing to about an inch larger around the quilt (if you are going to turn under the edge)then turn it to the front, pin well and stitch it down. when laying your sandwich out be careful to not stretch the fleece just smooth out the wrinkles...and baste well.
