Art supply junkie

It's a sickness I allow as long as it doesn't get in the way of creativity. Now that I have a better idea what I like I have put some severe limits on what I add and am starting to put away, sell and gift what I am not using. Mostly I just focus on drawing and painting every day. As much as I strive for minimalism I often fall short, especially when it comes to art and stationary supplies. This little box I got in London when I first moved to the UK and was waiting for my supplies to arrive from Boston via boat shipment. Now it is a contained collection of everything I need to get to art making. Usually in the living room while I watch TV with my husband in the evening. What is your shopping weakness if you have one?
