Everyone collects something don't they? Instead of hiding your collections away or letting them become clutter use them in your home decor.
Group your items as small groupings on table tops, shelves or the mantel. Try to keep the number small and interesting. After all your goal is to draw attention to your passion. If you have a large number of items then rotate them throughout the year.
For me, as a photographer and a lover of fine art, photographs and photographic art is something I collect. For me I use the walls for the larger images. The featured photos above are all scenes from Maui taken taken from the same beach on different days. Each is unique in its light and the weather, but location ties them together with a theme.
What do you collect and how do you display it?
