I just made up two 5lb spawn bags of maple sawdust with a dash of coffee grounds using proper gusseted, filter-patched polypropylene bags. Unfortunately I have a tiny pressure cooker, so tomorrow I'll have to sterilize them one at a time for about 2.5 hours each... but they should both be cooled down and ready by Sunday to be mixed with my 6 pint jars of colonized birdseed. I'll post pics tomorrow.
