I have been using string bags for my groceries for a couple of years now, and I always keep them in my shoulder bag. Sometimes they get tangled up in other stuff, which is why I invented this "life hack." I thought I'd share it here.
Two string bags:
Two string bags tangled in my shoulder bag:
I take an odd sock (who doesn't have one of these?) . . .
I put my hand in the sock . . .
and grab the handles of the string bags . . .
slipping the sock, pillowcase style, over the string bags.
Then I put the stuffed sock it in my bag where it acts as a very light and non-bulky cushion for whatever else I have in there. No more tangles!
[Notice that I put the most attractive book in my library in the bag?]
