Little Big Girl Studio has a great tutorial for an organizer wallet. I liked it so much I tossed aside a work in progress and made a little stack of them!
Look inside! There are little slots for cards, and that curved pocket is big enough to hold my iPhone.
The little notebook is just a plain 3’x5″ notebook. (I bought a stack of them from Walmart for 50 cents each.) I used a heat bond adhesive to bond coordinating fabric to the back side of the notebooks. (The back sides worked better because they were plain, so the printed stuff didn’t show through.)
I claimed this one for myself.
Go make something!
