The front is made of the collars and button bands - she has kept the buttonholes behind each button!
The top of the bag is made with the parts that have the stiffener fused to them which means that it gives a really firm top to the bag. The decorative flaps with the toggles are made from cuffs.
Here is the inside pocket rescued from another shirt! Maureen called the bag 'Hard Collar' because she broke a needle when she went over one of those plastic tabs found in the ends of some collars.
I'm sure you will agree that this is a fabulous bag. The only sad thing for me is that I recently had a clear out and threw away loads of collars and cuffs from the shirts I have recycled into quilts. I really want to make one of these bags!
