Usually stitched with rug wools. Stitched with a variety of threads. Petit point - meshes 18 to 64 per inch. Stitched with a variety of threads. Gauge , or mesh, refers to the number of threads per horizontal inch from selvage to selvage.
Selvage is the heavy woven sides of the canvas yardage.
This selvage should always be on the right or left side of a printed or hand-painted canvas design, never on the top or bottom. Canvas threads are not woven evenly, so turning the canvas will make your stitches wobbly. The canvas is always cut 1.5 to 2 inches larger all around than the design area, regardless of the mesh. For example, for a 12 X l2 worked area, the cut size of the canvas would be 14 X l4. This allows for finishing and ease in handling the canvas while stitching.
