blocks from fleece for quilt

Can anyone tell me if they were successful in cutting squares of all
different fleece fabrics to make a quilt top? I was thinking I could
make some squares 10" and then smaller ones to make a 4-patch and
alternate them. I have been saving fleece for this for ages, but now
that I'm ready to do one...I'm not sure how to proceed. Serging or
sewing? If sewing...what thread, what stitch length, what seam
width? Any suggestions would be wonderful. Also, if anyone has a
photo of one they have done, I would love to see it! TYIA!
