The banana invitations were my favorite part! The peel was made of felt and I came up with a pun for the wording - corny, but I love it! I got the jumping-off point for this idea from a jungle theme party described on the Parents magzine website.
I had to include a pun in the thankyou notes. They were a very simple creation, really. I think my creative energies are tapped out when it's thankyou note time and they always seem to get the short end of the stick. I found the stickers on Ebay. They were scratch and sniff stickers, but they were also "vintage" (probably from the 80's?) so their smell and their adhesiveness were gone. Cute, nontheless!
