Sue Spargo created this tool to help with some of her signature knotted stitches - specifically the drizzle stitch - which is why she calls it a drizzle pad! This sweet puck could work well for a variety of woven and knotted stitches, especially where a stabilizing needle is utilized.
You could also use this tool in a variety of mending techniques as well. The puck is thick enough to be used when needle felting is required and could also serve as a protective barrier so that when you are stitching, you aren't catching the fabric on the back.
