I collect quilt pins as well as other types. Inexpensive way to remember a place you've been. Quilt stores used to have their own pin and also quilt shows, not so much anymore. I attended 12 years of quilt shows in Houston when I lived there and have the quilt show pin from all but one. They made a limited number each year and I got there too late one year. I display the pins on wallhangings.
