Yep, this bag knows everything. It knows your row number, the chart for your stitch pattern, and where you are in that stitch pattern. Unlike the other know-it-alls in your life, it will gladly share information with you by displaying your row number and a chart for the current row of your stitch pattern in lights! (Though of course there are limitations; you can generate a custom chart for the bag, but only for stitch patterns up to 10 stitches wide that use k, p, k2tog, ssk and sk2p).

Here’s how it works: a tiny computer chip gets connected to LEDs using metal-coated thread. The computer chip sends signals to the LEDs—all on (knit), all off (purl), flicker (yarnover), etc.—and poof, your knitting pattern lights up. Want to see the next row? No problem! Just press the button and the next row displays. Need to turn the bag off until tomorrow? No problem! It saves the row you were on, even if you remove the battery.
