I'm "cold sheeping" and trying not only to not purchase any new yarn, but I'm destashing, too. I don't know what I was thinking when I loaded up on Bernat HandiCrafter Cotton gigantic balls when they were on sale at JoAnn some years ago. They are definitely "craft" yarn and not garment quality cotton. When I used my penultimate Swiffer pad, I remembered that I had knit and crochet patterns for reusable pads and that I had tons of yarn that was perfect for the purpose. Kismet!!
I made a few of these handy little helpers. Today, when I mopped my floors, I was more than satisfied. It cleaned well and after a rinse in the sink, I will toss it into the washer the next time I do laundry.
The crochet pattern I used was free from Lily Sugar n Cream. I should say, the first pattern I used was that one. When I completed it, I didn't understand why it needed to be constructed in 3 pieces.
So the subsequent ones, I improvised as a single long rectangle, then I single crocheted the ends inward. I fiddled with the number of chains with which to begin for the correct snugness, but it wasn't difficult.
Unfortunately, now the Swiffer Wet Jets have dual sprays, and I wouldn't be surprised if the new design isn't intended to dissuade crafters from making these "socks." Glad I've got an old one.
