You might be wondering what the little grey squares on the canvas are. They are rare earth magnets; small but quite powerful magnets used by needle pointers to hold their needles. One on each side of the canvas holds gently but firmly, preventing the canvas distortion that we used to get from sticking our needles through the canvas.
I tried taping my design to the back of the canvas, but the magnets work better. It’s easier to make small adjustments to the design’s position. This is necessary because no matter how carefully I make the design up, it never perfectly fits the point size of the canvas. Thus I need to shift the design round as I paint different areas.
Rare earth magnets are stronger than ordinary magnets, and very light! Ordinary magnets have trouble holding through any thickness of material; these rare earth magnets even hold through my 9-year-old niece’s fingers!
