I`ve been thinking about this too with my house temps going up and down. :wha:
I thought about making some kind of insulation box just big enough for my ferm bin or jar.
Anyone got any ideas or done something similar?
Probably too late now, but i would sit outside my nearest bottle bank and wait for some old chap to come along to recycle his old bottles and mug him :lol: well not literally but explain what you want them for and he`d be more than willing to let you have them. 8-)
me... a cheepskate... how...
