It really IS easy to make "yarn" out of plastic grocery bags! If you want to know the technique, please leave a comment (on the blog post itself, not on facebook if this is posted there). I knit up a quick gauge so I could see how it felt. It's not bad. Takes a little getting used to, but overall it's pretty easy. I did garter stitch on US 8 needles, casting on 10 stitches. I think I'm going to find a bunch of bags and make a bag! This was with one plastic bag. Best thing about it? Well, besides it being recycled of course! If you need more "yarn" you don't have to do a lot of work, just loop more on!
Maybe I'll make a door mat for wiping icky winter feet on!
