Things You'll Need
6 mm knitting needles
1 ball worsted weight yarn
Re-usable wet and dry Swiffer mop cloths are expensive and wasteful. A washable, reusable wet/dry cloth can be knit in no time with basic knitting skills. The sand stitch texture means these cloths are just as effective at polishing and mopping as bought versions, and better for the environment than one-use-only cloths.
Wind your yarn into two smaller balls as the yarn will be held double.
Cast on 14 stitches with the yarn held double.
Knit in sand stitch (knit all stitches on the odd-numbered rows, knit one, purl one on the even-numbered rows) until the piece measures 18 inches long. Bind-off all stitches, and leave a long tail of yarn at the end.
Fold the each end towards the middle of the right side of the knitting, overlapping by 4 inches on each side.
Using a yarn needle and the yarn-tail or separate strand, sew the 4 inch folded seam on each side, sewing 4 seams in total. Weave in the ends of yarn and flip the two folds right-side-out.
Sand stitch has a good scrubbing texture, but any stitch can be used.
Aim to make the cloth fit snugly around your Swiffer as it will stretch a little when wet.
Make sure the yarn you use is color-fast or use white yarn as cleaning detergents will make some dyes bleed.
