I don;t know if this weird at all since I don't drink, but I love collecting wine bottles. I think that there is just this simple elegance to the shape and color of a wine bottle. Also, they can be used in plenty of DIY's like vases and hanging lights, etc.
Another thing I love collecting is paper. I love art, so when it comes to pretty paper, I'm a fanatic. I love the different textures, materials, prints a paper can be made into, and I just think that it makes a drawing so much more interesting at times if pretty paper is utilized. c:
