So the other day I asked "Why?" and he said "Because we can make something with it!".
Very noble, I wasn't going to let that one go! I explained that I wasn't going to refashion everything he outgrows, but I may be able to do something to store his growing Bakugan collection if he let me think about it.
I took a pair of pants, cut it all up and made a small messenger bag with his old judo belt for a strap. The flap is the front leg which had a decorative faux-pocket and I used a back pocket to store the cards.
Heck! I didn't make just one, I made 2, my nephews' birthday was last week. It's shipping today.
