I have been carrying my coupons for restaurant and store discounts in an envelope in my purse. I could have kept changing the envelope when it started to fall apart, but instead I decided to make a quilted coupon holder.
Velcro was used as the clasp. The inside is lined with the heavy interfacing which is used to make fabric bowls. I cut it into pieces and allowed space between the pieces so the holder would fold neatly. The only problem encountered was the binding. Like a book binding, it needed more binding on the outside than the inside. The problem was solved by sewing that section by hand.
This is the inside of the finished holder.
