A friend of mine makes these carryalls from recycled feed bags. I asked her to make a few for me to load into the shop. This bag is made from our grain bags. We give the ewes grain in order to give them the nutrition they need to prepare for lambing as well as to produce milk after lambing.
They are 5" deep, 15" wide and 16.5" tall with a nice handle. I use mine for groceries, but they have all sorts of utility.
Very hard wearing, best to hand wash.
