Crocheted Hot Pad
1 Skein of Patons Classic Wool (I got 3 out of one skein)
5mm crochet hook
Darning needle for sewing the one seam shut
Gauge isn't a big issue, although you don't want to go loose, tighter is better.
Set up row: Sc in 2nd ch from hook, sc in each ch to end of row. Turn work so that the bottom of the ch is facing up. Sc in in each ch. 80 sc.
Next Rnd: Join to next rnd by sc in next st, sc in each st around.
Continue on in this manner. The two halves should start curling in so that it creates the other 2 corners. It will fold up so that the two sides that you have been crocheting meet up in the middle of the back. Once this happens crochet to one of the corners you have left, cut yarn leaving a 12" tail. Fasten off. Whip stitch the hot pad closed. Weave in ends. Done.
Now I recommend using a natural fiber and not acrylics as acrylics will melt. I haven't tired it with cotton yet, but it can be done.
