My husband enables my habit - I don't WANT him with me dragging more fabric to the cutting board! Unless I'm feeling wealthy that day, of course! (I do our budget - he doesn't have a clue.)
When I get a kit - or even just browse through them, I'm learning about colors and patterns and lights/med/darks. I love looking at fabriccafe.com for that reason - seeing what goes together that I wouldn't have thought of. Learning, learning, learning!
