Cereal boxes, cracker boxes, fruit snack boxes, anything with a sack inside so the box stays clean.
There are lots of fancy ways to cut up your boxes and turn them into cool gift boxes or gift bags.
I'll probably just put the presents inside and wrap them like normal. Because it doesn't sound like fun to me to cut them up and glue them together again.
But if it sounds like fun to you...send me a present in one!
