How to get paint out of very small designs in wood furniture

I have used toothbrushes, toothpicks, even the little tiny screwdrivers, as long as you use a gentle touch so as to not harm the small designs on the wood should work.

nut picks and anything metal that works. Wire brushes etc.used with paint remover

dental picks. can get them at hardware store.

You might want to use a stripper, like CitriStrip, with a toothbrush.

strip and refinish

Use a Q-Tip dipped in Citristrip

I have used a sandpaper wrapped awl to fit into small spaces; sometimes a small screwdriver depending on the space involved.

Dental tools.

I will probably be in the minority here, but, I use a very soft scrub brush for detailed areas. It works. Try inexpensive ones like the dollar store has, since they won't be very stiff and it's something you can toss.
