Sc the sides together with the front of the coin purse facing you.
Finishing touches. Crab stitch edging.
With the front of the coin purse facing you join at the left hand corner , ch1 and begin crab stitch over the inside top, down the right side and the bottom.
Then with the back of the coin purse facing you(would be on the front if the coin purse is buttoned closed) Join on the left where the coin flap begins, ch1, and begin crab stitch around. (On the coin purse on the right I did not do the crab stitch across the top of the inside.)
Weave in ends and sew on the button.
