I will not be putting a backing on this rug as it will be on a carpet. I used a Susan Bates hook in size N. Which is a pretty large hook. I started with 40 chains and did 1 sc in each stitch across and 3 sc in each end, for the first round. The second round was the same except in the 3 stitches on the ends from the previous round I did 3 sc in the 1st st in previous round, 1sc in the 2nd st from previous round and 3 sc in 3rd st from previous round. This started my corners for the rectangle shape. There is no pattern as I just worked it as I went.
It is not finished yet but what you see done is 2 full skeins plus 1/2 another skein and I have two skeins left. When I use those up it will be finished. I have no plans for a border.
My next project will be a shawl.
