Blank needlepoint canvas interlock is a high quality needlepoint canvas that can be used for most projects. Interlock needlepoint canvas is best used for continental or basketweave stitches, rather than stitches that might require movement at the canvas thread intersection (where mono canvas should be used). Interlock blank needlepoint canvas is available in a variety of mesh sizes. Use mono canvas if the item you are making is going to get a lot of use, or wear and tear.
