Great info! I'd like the duster to be less bulky, and never thought about attempting to remove the felt-like material. Curious - I wouldn't want to attempt any "scrunching" effects, but what distance/length of a lighter would you say is best for just burning away the felt?
I may try the emery for roughing it up some. The only thing I did to customize my duster was drybrush/paint it with a flat acrylic, "muddy up" the lower areas, and create a detailed black leather/threaded piece to cover up the simple brown patch SS put on the right sleeve (I was proud of that little bit).
Cheers, hoodonit!
