Well, I'll show my ignorance, and give an excuse of only digi-scrapping for 2 months, and say Brushes. I kind of know what they are, but have no clue what to do with one when I get it in a kit. And I also don't get why there are Brush kits that actually look like stamps to me. Like a brush kit that says "frames", well, sure I know how to put a frame on, but why is it called a brush set?
So I guess a tutorial explaining everything would be just what I need.
