These handy devices create a laser beam that appears just in front of the needle, showing where the stitching line falls. Helps you sew straighter and with no marking. Perfect for straight-line quilting, stitch-and-flip corners, dot-to-dot quilting, stitch in the ditch, seam allowance, topstitching, and more even sewing zippers. The laser line can be used to sew straight lines to make half-square triangles (HSTs) or stitch-and-flip corners without drawing the lines corner to corner. The green laser is proven to be gentler on the eyes and is better for people who are light sensitive or have other health concerns with red lasers (If you're concerned about sticking the Velcro directly onto your machine, you could always put a Command strip on first, then just stick the Velcro to that!)
