Lady Macbeth's favorite dishrag

Lady Macbeth: "Yet here's a spot... Out, damn'd spot! Out, I say! - One; Two;" - Macbeth Act 5, Scene 1.

Obviously, Lady Macbeth was without this knitted dishrag:

Measuring 7" by 7", this little beauty will clean any spots on dishes you've got. It's quite resilient and durable, and can be tossed in with the laundry to clean.

You will need:

• a 100% cotton yarn in your favorite earth-tone color (i.e. sage green, brown, dusty gold, etc.)
• U.S. size 6 knitting needles
• Size I/9 (5.50 mm) crochet hook
• Scissors
• measuring tape

Cast on 40 sts.
Knit in regular garter stitch until square measures 7" long, and is even on all sides. Bind off.
With crochet hook and same color yarn (or, to provide a bit of contrast, choose another cotton yarn in a different color), crochet an edge around all four sides only once, cut yarn and tie off. Weave in ends.
A little puckering around the finished edge is normal.

Now go attack the pots and pans with all the subtlety and force of Burnam Wood coming to Dunsinane ;-)
