I always just ask DH what he wants. He generally wants art books, or a machine(tattoo) by so and so, some fancy art supplies he won't order normally, ect. Last year I got him a cast iron drafting table from 1903. It's his favorite gift I have ever gotten him. That was actually a surprise! He always asks me too. I really like being taken shopping and spoiled. That's also my favorite b day present!
