Here’s a quick and easy way to dress up a dollar store dishcloth — just crochet a simple border around it!
I first took a length of my 4-ply cotton yarn and split it into 2, so it was only 2-ply, then used a needle and made a blanket stitch edging evenly around all 4 sides of the cloth. This gave me a base to work my crochet stitches on. Then I worked my stitches as follows:
Round 1: Sc in each stitch around, slip stitch to beginning sc.
Round 2: Ch 1, (sc, ch 1) in each st around, slip stitch to beginning sc. Fasten off.
