This is a tough crowd...not sure what side of the love/loathe columns my own creations would end up on!
I suppose I'm safer to just list mine as stuff I use and don't use.
Stuff I use:
Anything that combines needle art/sewing with card making
Shabby Chic vintage
Kraft cardstock (Pure Luxury is the best!)
Flowers and pearls
Stuff I either don't have or don't use:
Solid image stamps
embossing powder and all things messy
Lots of fancy tools
I can't think of a color I don't like. It always turns out that as soon as I say I don't like something, I'll see an awesome creation that someone made with that very thing I said I didn't like, and then I'll want it, too!
