I love to use my Swiffer, but I hate the disposable covers. So last night I made a pattern out of 100% cotton yarn, that fits on a swiffer. I thought some here might be able to use it. Its machine washable, and it works great.
Re-usable Swiffer Cover
Size I hook and Sugar n Cream yarn - any color (its a *really* good use for scraps)
Measure your swiffer width, and add 4 inches. (my swiffer is 10 inches across.. so I crocheted 14 inches worth).
Chain 18 st. In the second ch from hook, sc in each st - 17 st across.
Repeat this row until you reach your measurement. I stretched mine out before I measured, because the cotton stretches as is, and I wanted a snug fit.
Fold over short edges 2 inches on each side(wrong sides together), and sew the edges closed, so the cover can slip on your swiffer and stay on securely.
