One of Larkin's favorite recent discoveries is finger gloves! These are mostly designed to protect fingers from the heat that develops from friction as metal is worked. They are thin and Larkin can pull them firmly down over their itsy bitsy child-sized fingers (not gonna lie-- it's hard finding protective equipment in their size!) so they maintain finger dexterity. Added bonus: they will shred before fingertips if those rotary tools end up where they shouldn't. ;)
