Follow along with Eileen Roche and her Craftsy class The Machine Embroidered Quilt with the Perfect Alignment Laser. The Perfect Alignment Laser allows you to hoop square easier with exact centering and stitch precise seam allowances.
"PAL makes it so easy to hoop square. I just line up my inner hoop's horizontal and vertical center markings with the illuminated crosshair, firmly hold the inner hoop and insert it into the outer hoop. Now I know my fabric is square in the hoop. At the sewing machine, PAL helps me guide the fabric edge for precise seam allowances. I don't know how I survived without PAL all these years." - Eileen Roche
Each Perfect Alignment Laser includes an ssembled lamp featuring gooseneck, 3 AAA batteries and a USB connection.
