How do I put a gasket on my canister set?
This is a stupid question, but I have had this canister set for 40 years, back when they had S&H green stamps. Is there any way I could add a gasket or seal around the rim to keep flour and sugar fresh? I could buy a new set, but I never found any that I like. I only keep the flour or sugar for a short time in these, then if I haven't used it, I throw it out. Kind of a waste.
