Nana, dunnno if this is worth a go, but we use heaps of velcro with our horse rugs and bandages and what gets fluff and hair out of the hook (rough) side is one of those paddle style dog brushes. The ones that have the really fine wire teeth. (they sort of look like a 'bed of nails' type thing??) just run it through lightly so it doesnt catch on your stitching. Failing that, try a comb, but use the end with the teeth close together...... HTH
