I wouldn't go the 1 lb route, as it turns out watery and very low abv. (one of my many failed experiments in a quick mead) I've gone to 4.5 lbs per gallon (stuck ferments galore, but a whopping 15% sweet mead), but you can go as low as 2.5 lbs.
As a matter of fact, when asked this question the owner and chief meadmaker at Rabbits Foot Meadery said that 2.5 gal of your favorite honey, some nutrient, and a good fermenting yeast, like lalvin k1-v1116 or champagne yeast will yeild a very good, semi sweet, drinkable abv mead. Aging is key though. I've learned to brew beer just to keep my mind off the dusty gallon jugs in the closet
