Waste Canvas is 14 count & is used when you want to cross stitch or embroid onto a fabric that does not have an obvious open weave i.e. T shirt fabric or on a shirt. There are a number of clips on You Tube on how to use it. Just pin or tack the Waste Canvas onto the fabric, then cross stitch or embroid your design through BOTH layers of fabric. When you have finished soften the fabric with water and using tweezers remove all the threads of the Waste Canvas. Wash the design gently to settle it into place. It works best if your stitches are a little tighter than normal so that they sit tight against the fabric after you have removed the Waste Canvas. If you need a different size to what is listed, just use the Contact Us page and we will give you a quote.
