I have just started following your blog and would love to join in! I get interested in so many crafts, but end up never doing them - so maybe this would help push me?
The only problem with having a SET craft is if I don't have the necessary items (I have promised myself no more buying!); then a theme would help. Could you do a double prompt? Stating a theme and a certain craft? Then I could do one of the other ... or BOTH!
