I made this super simple lego gift box with the Stampin' Up! gift box punch board. It makes it really easy to get boxes the right size and in any colour or paper. I used the Boys will be Boys stamp set to make the cute tag to go with it.
If you are making this, I recommend buying 12 x 12 card as it gives you the widest options of box size. I used my 1.5 inch circle punch too.
