I just finished quilting two pillowcases using fleece (I found a piece of fleece in my stash that was the right size for the two cases, and I couldn't remember why I purchased that fleece so decided to use it) I do not like how the cases quilted up. The fleece did not "fill" between the quilting lines like normal batting so the quilt block fabric has a little puff on top of the very flat fleece. I'm thinking of frogging the cases and quilting again with my beloved Hobbed 80/20.
