I made this bag last winter. Much as I liked its capacity, looks, and washability, it did not get used because it is so big that when full, it dragged on the ground. The handles were not long enough to be worn over the shoulder. So it mostly sat in the car, last of the reusable shopping bags to be chosen.
When we were driving up to visit my son yesterday, I grabbed the leftover yarn and added a longer handle to it. It's just one simple strap that is long enough to go over my shoulder, wide enough to be comfortable.
Now this bag can finally get used!
