Knit one, purl two. Whatever, the Hacienda Heights Library is getting back to the Knitty Gritty Basics of Knitting.

The four-week workshop will teach teens how to cast-on, cast-off, knit, purl, increase, and decrease. Classes will be held at 3:30 p.m. Mondays, beginning Sept. 15.

Registration has already begun. Supplies will be provided, but teens can bring their own materials. Size 8 single point knitting needles and acrylic yarn are recommended.
