Where does one find jam jars?

My Mum always used to have hundreds under her sink - look for a neighbour old enough to remember WW2 and hit them up for their stash.

I wish...unfortunately we moved to a brand new estate, don't actually think there is anyone over 45 within 10 kms!

Will hit up the ladies at the op shop

There's a secret jam-jar sisterhood...you won't be admitted until you've cooked up at least three seperate batches of jam, chutney or marmalade. Then the jam-jars will start popping up uninvited, expectantly waiting for jam .

catering supplies shops sell them new
