I make dish scrubbers all the time. Here's my pattern. Chain 5, join to make a circle. Chain 3, then 2 DC in same stitch. 3 DC in each stitch around the circle, join. Chain 3, then 1 DC in same stitch. 2 DC in each stitch around the circle, join. Cut yarn and tuck in the tails! (Weave in the end of the yarn.) This makes a nice ruffly scrubber. If you don't want it as full, just do less DC to make it flatter.
