It's Jo here this week to set the dare, the design team may have groaned a little when I picked the theme, but I don't think that it is too bad :)
I would like you to use some sort of tartan on your cards, fabric, ribbon, paper, even a piece of an old tartan rug(!)etc.
The design team (amongst a few little groans) have, as usual come up with amazing array of cards featuring tartan.
Have a good week and I can't wait to see what you create.
