What kind of string do you use for canvas embroidery?
Use embroidery floss on tighter canvas mesh-like #18 and congress cloth. Base the number of strands you should use on the size of the canvas and the stitch you are making. There is no cut-and-dry formula for how much to use. You should experiment on a scrap piece of canvas until you are happy with the thread coverage.

Fabrics for embroidery
As a rule, natural woven fabrics are usually best for hand embroidery techniques. Choose from cotton, wool, linen or silk for your background and select the appropriate thread-count for your technique and threads you are using. Make sure you prepare the fabric properly.
