The smallest bifold wallet (that I can make)

Someone once inquired what was the smallest, yet fully functional, wallet I could create. After several trials, here she is at 3.75 x 2.5 inches, roughly the size my cell phone!
Though teeny tiny, I managed to cram in eight credit cards, a wad of cash and a small handle of coins in the three pockets and zippered compartment:
I have a silly habit -- to make everything in twos or threes. It's more efficient and results in better photo layouts :) I think the fabric is a 1930's reproduction.
