Need to remember this - a balloon curtain for kids to wake up to on their birthdays! Another take, once all guest arrive, hang balloons and the guest of honor walks through the balloon curtain. or any party/bridal shower
Baby shower idea: Guess the baby's birthday! Great way to replace a guest book. You could use stickers of a pacifier and/or a rattle. Each person placed the sticker on the date they predicted and signed their name. Perfect to put in a scrapbook, too!
Have guests write message to the birthday boy/girl. Could do a new book each year as a keepsake. I have the Places you go for my daughters school years but the birthday idea is super cute too! Seuss had a birthday book!
