Quilters and crafters, this little tool is a total game-changer! This set includes 60 silicone adhesive discs – 30 large ones and 30 small ones. You just peel off the backing and stick them onto the back of your quilting rulers, templates, or any acrylic crafting guide. They create a gentle, non-slip surface that grips your fabric like magic. No more sliding or shifting while you're trying to make that perfect cut with your rotary cutter, which makes everything safer and way more accurate. The silicone is soft, durable, and won't peel off your tools easily, but you can remove them if needed. They work on any smooth ruler or template and are a must-have for anyone who uses a rotary cutter for quilting, sewing, or other fabric crafts. Keep your cuts precise and your fingers safe!
