I just discovered I.Candy!
I.candy offers a HUGE selection of hand-stretched canvas artwork at VERY affordable prices. You choose the artwork you like and then you can choose your size, your shape, and, in most cases, even your room's custom Benjamin Moore colors!
You have the option of a wood or metal frame, or you can go completely frameless.
I like the fact that your shopping can be done from your computer, and there is no need to go from store to store to store and risk coming home with nothing.
