I finally finished my draft blocker for the front door. I started this back in June with left over yarn from my afghan I was knitting on the tread mill. I just added scraps in no order and when the scraps started getting thin I went on the scraps from my next afghan. All yarn is Brown Sheep Bulky and I used about Four skeins worth by the time I finished. I ran it through the washer on Hot twice and then the dryer once. Then I filled it with feline pine cat litter (around 15 pounds worth!) and seamed up the end with a yarn that was close in color. It's pretty perfect.
The pattern can be found http://www.lionbrand.com/patterns/60492A.html?r=1 in it's original form. I made mine larger so I could knit it on circular needles and avoid a seam up the back.
I really like it! I got to use a bunch of scrap yarn and it might help keep the heat costs down a fraction - and our house a tiny bit warmer.
