I began brewing BIAB with a starter kit for 1 gallon batches. I would like to move up to 5 gallon batches, but my original brew bag would be too small for the quantity of grains required.
I know nothing of "needlework", I can buy material and give it to someone who would make it for me, but i need to buy the correct amount/dimensions of material.
What amount of material would I need to buy and what would the pattern dimensions be to make the actual bag?
