Due to the nature of the crepe paper, the wire wrapped inside each leaf really goes a long way to keeping the leaves looking "fresh". I would not recommend doing this a long time in advance. I did mine the day before the event and was able to leave it hanging overnight. It is a bit fragile and I would not recommend traveling with it...it is one of those items best assembled in place at the location of your event.
Here are list of the supplies and resources where you can get them:
CREPE PAPER ROLLS: CARTE FINI IN LEAF AND METALLIC GREEN/GOLD
GREEN GRAPEVINE WIRE: HOBBY LOBBY
This backdrop would be perfect for any Jungle Book themed birthday party, a Where the Wild Things Are birthday party or even a Dinosaur birthday party. The possibilities are endless! So have fun and be sure to link up so we can see your masterpiece in action!
