Tapestry kits and canvases. Tapestry is usually worked in tent stitch, which is like ‘half cross stitch’, in other words only half of the cross is stitched. It is often worked on a printed canvas.
Kits usually contain everything you need to get started - fabric, threads, pattern, needle and instructions.
Canvases are only the printed canvas but will usually give you a 'shopping list' of threads needed.
