Scrubbies, or scouring pads, are crocheted with one yard of nylon netting and a size N crochet hook. Cut one yard of nylon netting into 2-inch-wide strips. Knot the strips together to create one continuous strand. This nylon "yarn" can be used to make circular or rectangular pads.
To crochet a circular pad, place a slip knot on the hook. Chain four stitches and slip stitch in the first chain to form a foundation ring. For the first round, chain three (which counts as one double crochet) and double crochet 11 more times in the ring. Join the round with a slip stitch in the third chain.
For round two, chain two (which counts as a half double crochet) and half double crochet in the same stitch as joining. Continue around the circle with two half double crochet in each double crochet. Join the round with a slip stitch and fasten off.
Make two identical circles. To join the circles, place the wrong sides together and slip stitch in each stitch around. Fasten off and weave in ends.
To create a rectangular pad, chain 10. Turn work and skip the first two chains. Half double crochet in each of the next eight stitches and chain two at the end. Turn work, skip the first single crochet, and half double crochet in the next eight, including the top of the chain at the end of the row. Continue in this fashion until the pad reaches the desired size.
