[MODNOTE: Also see post #24 for a spreadsheet by bionut which does some of these calcualtions for you.] This is a step-by-step tutorial for generating a fabric pattern for the two main pieces of fabric you will need to sew a fustrum(truncated cone)-shaped brew bag. You will cut one circular panel t...

I'm a somewhat novice sewer with a sewing machine, but I've done some bits of upholster...
