When I travel, now that I can afford to buy modestly priced art, I will often purchase art. It is a way for me to remember experiences during my travels. One etching that my father has in his home is from a day we spent in a small town in Holland searching for art. He found it, I bought it and then felt so bad about snatching it up from under his nose I gave it to him. We both smile when we talk about that etching and that day we spent looking for art.
I also trade with local friends who are artists usually when they have just finished displaying their work at an event.
I do not hang my work in my home, although most of my family have pieces I have done over the years. Usually given as gifts when they particularly expressed an interest in a piece. I really like visiting my work in the homes of my family.
