Two things that are hard on rotary cutters, paper and polyester fleece and other synthetics. I try to remember to replace the blade if I have been cutting fleece. I use fleece for some of my quilt backings and find when I cut the cotton it makes a mess; skips, rolls the fabric along. Change often in that case.
