Can you cut your wires from your heating blanket tie them together to form 1 wire and turn it into an earthing blanket?

No, you should not cut the wires of a heating blanket or attempt to modify it in any way. This can be extremely dangerous, as it poses risks of electrical shock, fire hazards, and damage to the blanket. Earthing blankets are specifically designed for grounding purposes and should be used as intended without alterations. Always prioritize safety and use products according to the manufacturer’s guidelines.
