Do you have a collection? Maybe two or three. . . or twelve. I believe a true collection is planned, cared for, shown off, admired and loved. You do this by carefully selecting pieces, planning where and how you are going to display them and then enjoying it.
If you need some inspiration on how to display your loved collections, check out Pinterest. I found these examples.
