I ended up using some natural lightweight silk fabric as I knew I needed to be able to see through the bags to make it easy to find what I was looking for in the fridge (and hopefully avoid a bag of long-forgotten, now-unidentifiable, slowly-decaying produce at the back of the crisper)
Because the silk is so light weight it doesn't add anything extra to the weigh-in at the checkout and the checkout bloke can easily see what is in the bag. It also has meant that all those things I never bothered putting in a plastic bag no longer get constantly handled by aforementioned checkout bloke or stray children that end up in the trolley. Green leafy things obviously do not store as well in these bags but things like green beans last much longer and do not sweat like they do in plastic.
I had the silk in my fabric stash so I'm not sure how much these would cost to make. I had originally thought I'd just use an old sheer curtain but now I'm really glad I used the silk as they not only work really well but and have been a hit with the silkworm breeder who has enjoyed seeing what a worm can create.
Plus they feel amazing.
So that's my quick sewing job today, cutting out more produce bags because I've started to use they for all sorts of things, although I did draw the line at them being used for carting around matchbox cars.
More creative spaces here.
