Last week, we butchered a chicken, but had to bring it inside because it was too dark. I cut open a cat food bag and did it on the kitchen table. No mess! After finished, just wrapped the unused carcass bits up in the bag to transport it back outside.
I have now learned that my husband, when going out hunting, uses his food bag apron as a seat. Silly man. Now, I just roll one up for him and he takes it with him and unrolls the bag to sit on the ground so his tush doesn't get wet. This could be used for fishing or camping or whenever you might be sitting on the ground. Compact water barrier.
