Cards for Grandmothers on Mothers day?

I'd like to make cards for the grandmothers this mothers' day with my 22 mo old DD. Anyone have cool ideas for cards that can be sent in the mail?

I was just coming here to post a blog that had really cute crafts and saw your post. I think I'll be making these tomorrow with my kids:

Really neat-thanks!

I do a handprint on a regular card
