love the dinosaur! im considering sewing some similar dinosaurs on to pillowcases - lucky i saw your post! my questions is...do you wash felt first? does it shrink/bleed? i dont want the pillowcases (a gift for someone) to be all ruined after washing!
i haven't sewn them on anything but bags ever. most of the bags i've given away as presents, so i can't really answer your question. i would suggest makeing a test patch and see what it can withstand as far as washing and such.
