I have about 6 dozen canning jars and I know I won,t have enough from my garden this year to try out some caning....my question is what else can I use them for...I hate to sit them sit there in the boxs doing nothing...I will be washing them up till I get some replies...as i did get most of them from yard sales...and I have a shelf that once they are filled with something that they can go on...and no we don,t have a farmers market up here or I would go pick or buy fruits to put in them and make jams and such(frozen thundra here)....I thought maybe rice or barley and would I have to vacuum seal the canning jars and how would I do that...
