Photos are great, but have you ever thought of commissioning a piece of art as a way to display special memories? I found a few great artists who offer commissioned portraits.
Alan Schuler features house portraits on Etsy. A custom watercolor will only set you back $45. This would be a great way to remember that first house or maybe your childhood home.
Susan Woodard does some amazing watercolors of children. She doesn't include facial features, so I think her best portraits show children engaged in a favorite activity. Her work is a bit more expensive, but a smaller watercolor is still pretty affordable for original art.
Miss Black Eyes is an Etsy shop that does portraits in oil. I love her brush work and attention to detail in the faces.
A custom portrait can be really any person, moment, or place special to you. I think its a perfect addition to any art collection.
