Skirt/Apron Swap Cards

I'm going to a stamping day-long event this weekend and will have the chance to swap cards with other cardmakers....so I made up a couple dozen of these cards to bring.  I think they are cute and different - while I was making them I was thinking of other things I could do with this template too....here's what the whole pile of the cards look like, and then the rows I put the 6 colors into...

Here are closeups of some of the apron/skirt cards:
