I recently discovered the wonders of a carrot holder. It sounds similar to what your mind might imagine when I say, "Carrot pen." I thought I'd take the plunge and get a custom one from AshBush Lettering & Design. Hindsight: I wish I did something funky and not so safe in my color design, but the relief it has brought to my double jointed fingers is immeasurable.
This baby dappen dish. I never knew how much I needed it until I had it. GET ONE. It holds the perfect ink amount without wasting half of your ink (like me for way too long...) The other plus is that it is glass and thus, really easy to clean.
