Creative Ways to Give Money as a Gift

I send holiday money gifts to my nephews who live a couple states away.  I am always trying to find fun stuff. The first year was the best!  

I sent $100 in ones.  I got a large box (watch out for shipping cost, or get a smaller box) and a ton of old magazines or news paper.  Tear out and crumble up each page of a magazine and throw in box. I used about 7 magazines to get the desired fullness.  Then I crumbled each $1 bill up and threw it in the box.  Then stir it all up so they have to SEARCH for all of them and then uncrincle each one! haha. It's also funny because they have to work together.  

Wanna drive them crazy? I thought about putting an odd number of dollar bills in like $43 or $98 haha.  They will keep looking for the last couple dollars!
