Thanks for all the great ideas! Didn't realize this thread was going for so long...
Here's what I sold last year and did REALLY well:
hanging wall calendars
acrylic frame desk calendars
recipe card books (bind it all)
This year, changing it up a bit:
hanging wall calendars- simple designs
frames (paper mache frames covered/w DP or washi paper)
gift card holder boxes
mini magnetic boards
Craft fair is held at my garage and hosts about 4 other girls plus my daughter. No charge on booths, so we all make $$!
