Measure out the length and width of your bangle. Add 1/4 inch all the way around to fold over on the sides and end. Cut this piece on the bias (at a 45-degree angle) on your fabric, to allow it more stretch and give.
Then measure the length and width of the inside of the bangle, and cut it just about 1/8 inch small on both sides, so the leather does not quite reach the full inside width of the bangle.
Glue along one inside section of the bangle and fold and press the fabric into the glue. When you reach the end, fold over the edge 1/4 so there is no raw edge showing. Let it dry.
Repeat on the other side, and use your fingers to push and slide the fabric to smooth out the folds. Make sure you let dry for 5-10 minutes in between gluing.
Now glue a portion of the leather, then place it on the inside of the bangle. Add more glue and press the leather against the inside of the bangle, covering up your raw cut fabric edges. Finally, printed fabric bangle is ready!
