Those who knit and crochet are familiar with two standbys: needles and yarn, but there's a lesser-known material in the world of needlework -- plastic yarn, or "plarn."
If you have a lot of old plastic grocery bags hanging around your house, you could use them to clean up after the cat, or line a trash can in the bathroom.
Or you do something a little bit more ambitious: cut them up and then put them together to make a ball of plastic yarn.
Elaine Selling lives in Derby, Connecticut, and is a plarn instructor. She's going to be teaching a class at the Kellogg Environmental Center in Derby on Saturday, October 15.
"The assumption is if you can knit with yarn, you can knit with anything," Selling said.
Selling said her experiences with plarn began by making a small clutch purse -- she's also made water bottle covers and a placemat.
On Saturday, plarn pupils will get a chance to learn the basics of making the yarn -- and they'll learn how to knit or crochet with the material.
Pre-registration is required and if you have plastic bags you're looking to recycle into plarn, bring them.
