I'll give it a go. But fair warning, I'm an odd creative person and not big into trends, period.
Stamps I can color with Copics
Elegant script fonts
Ink, ink, and more ink (see the love of color above)
ink techniques (reinker spread, mist and stamp, resist, brayering, daubing, stamping off, etc)
matching stamp/die/punch combos
Cling mounted stamps
GOOD QUALITY photopolymer stamps
TRYING TO LOVE:
patterned paper (love it; have a hard time using it)
glitter (huge mess!)
distressed (I'm a CAS type of gal)
frou-frou (like the look of others' work but I suck at it)
overly vintage (a few swipes of light brown in to soften edges is great; sanding, tearing, crumpling, not so much)
Unmailable designs (no family close by)
Anything missing body parts (like faces, heads, etc)
wood mounted stamps (take up too much space)
Cheap junk bought because it was well.....cheap.
Uh oh, I think I could go on for pages, LOL~ Better stop here.
