Designed to be used with the Maker’s Board, the handy Ruler and Gauge are also useful on their own. Magnets are embedded (without glue) in the back of each tool so they attach to the Maker’s Board, or any metal surface. In addition to measuring and checking knitting needle sizes, these tools can be used as straight edges on the Maker’s Board to help track patterns and charts. Plastic free, they are made of PLA (plant fiber, 100% biodegradable plant fiber, not water soluble) in a charming speckled linen color.
