I wanted this for my Diamond Paintings and what a difference it made! Just put under your painting and turn on. It made it so much easier to see the tiny squares. Now I can read the number/symbol on the square to know what drill to put on it. I will also use it on my cross stitch patterns so I can trace the pattern on the fabric and then stitch it out in the hoop. Works great, is larger and comes with pencils and an eraser! Great Buy!
