Here are two new cross-body bags, the first made from a leather vest, the second from a leather jacket. So much depends on the weight of the leather and the number of seams in the garment and these two pieces scored well in both areas. The vest was long and the back had only one seam. I still have enough of this great leather to be part of a second bag. The black leather jacket had more seams, but there was still enough clear leather to make a smaller bag with an exterior pocket. The red bag is 12″x9″x2″ and the black is 10″x8.5×3″. Both bags are lined with a zipper pocket inside.
I enjoy giving a second life to cast-off garments. And I try to use every inch. I have plans to make pouches and small cases from the remaining pieces still left on the cutting table. 
That looks way better as a bag than it did as a vest! Well done.
