Products that are designed for use with 18 mesh canvas.
A 18 mesh count canvas means that there are 18 stitches per inch. This may not sound like a lot, but to a stitcher it is a HUGE difference. If you consider that 10 mesh count canvas has 100 stitches in a square inch and 18 mesh count has 324 stitches per sq. inch.
Using a thick thread designed for 10 or 13 mesh canvas will be difficult to pull through the 18 mesh canvas. In this situation the threads slowly deteriorate as you pull them through the hole. It is best to use thread appropriate for the mesh you are stitching on.
