BIAB grain bags

Is there anywhere I can buy a grain bag for BIAB? It seems that most people are making the bags themselves & that's not really an option for me. I don't have access to a sewing machine & have no clue how to run one if I did. Looking for a bag for a 5g kettle (12.5"dia X 10"deep) & making 3g batches.

Hopefully someone can point me where I can buy one, kegs are getting low, the 3g indoor rig isn't finished & its too cold in the garage to use the 10g rig.

I believe Home depot sells a 5 gallon size for straining paint. For a nice big one you may have to find a seamstress??

Brewmaster's Warehouse sells them. I got the large one and it fits very nicely into a 5 gallon kettle. It is finer than the paint strainer bag and does a better job in my experience.

The one I got at Home Depot fit maybe 7 lbs of grain. I tried 9 I think, and it was way to tight- I got horrible efficiency. I'd get one that's meant for this (they're cheap), or I know some people make them themselves.
