DIY Jenga guestbook wedding idea! The sign "Build memories sign a jenga piece" was made from a wood board with decal letters. Just buy the jenga game and spread the wood pieces out on the table. Buy 5-7 thin point black sharpies so your guests can write on them. Buy a big fish bowl for them to put the jenga blocks in when they were done. Lots of compliments!
