Spot on Dot Magnifying Lens Set
The Spot on Dot is a set of magnifying lenses that help you to see the lines on your ruler better, and the fabric lining up under those lines. You can use the Spot on Dot with any of your existing rulers. The Spot on Dot is self-adhesive and repositionable. If the adhesive no longer sticks, simply wash with gentle soap and water to reactivate the reusable adhesive.
