Ok, gonna try this. I'm fairly new, so frankly, I only know what I like when I see it. Half of what I make, I don't like, but I'm getting closer now.
Colors that make me think of an orange Julius
Aqua/Turquoise (and related colors)
Ippity rubber. AMAZING stuff.
vintage things (but not "ephemera")
Whiff of Joy's "Willow" (and I don't even have her yet)
Most kiddie looking things except for when making them for kids
Glitz (I avoid glitter most of the time!)
