If you’re working with stone or wood, I recommend having additional adhesive to apply to the back of your stencil to create a greater bond. Have a mini plumber’s torch on hand to heat up the surface so the mask can bond to the stone with greater strength.
Another thing to consider if you’re sandcarving stone or wood is to go with a coarser grain or coarser grit of abrasive such as a 120 abrasive. You can achieve depth much quicker.
