Sewing - card wallet with an elastic

I made this card wallet for one of my grandsons for this birthday.  I made one earlier this month for another grandson but forgot to take a photo.  I used the dimensions that my sister, Sylvia, used for the ones she made. I uses 2 pieces of 5" x 11" - one the outside, the other the lining.  One piece of 5" elastic placed at 3.25" from the bottom edge.  You simply sew all the way around leaving an opening and turn it inside out.  The you stitch all the way around at 1/8" which closes up the opening.  Fold both ends to the middle leaving a bit of a gap so you can see the cards and stitch the ends of each folded flap to create to pockets.  You have to keep the elastic out of the way when sewing that pocket.  I made these for them so that they can carry a card or two along with a bit of cash with them instead of their larger wallets.  I added a little loop so they can use a carabiner to attach them to their backpacks or a belt loop.  Therese
