My daughter has chosen a 'mini' theme for her 8th birthday. I created a pillowbox (using a pattern I had from the internet as a guide) and Dana Zarling's Summer Colors kit papers and elements.
I shrunk down the 'invite' piece to be about 3/4" square and attached it to a magnifying glass with thread. I ended up hand delivering the invites to the girls as they were difficult to mail.
They seemed to be a huge hit.
