What to Do With Money Gifts?

I don't really like gift cards. Mainly because some companies have them reduce in value if they aren't used right away. 

My oldest nephew is at the age where he just wants expensive gifts, or money. 

One year I put $25 inside balloons. He had to pop the balloons to get his money.

My other sister - not his mom - gave him a money lei.

This year I begged asked my lovely husband to make a fighter jet. I tried a few steps and decided, "I can't get this to work."

He did. The tutorial is here.
