This is possibly where the hoarding factor comes in..I'm kind of over sentimental about worthless trinkets..lol.
Prime example: my Krankies button badge that I got from the Scottish comedy duo when I went to see their show and was one of the kids who got to go on stage. It was my 10th birthday...yup it's a pretty old badge..haha.
One of my collections has spilled over into the hallway..my Russian dolls. They are housed in a small cabinet (only half of which can be seen in the photo) and are often admired by visitors.
I've stopped collecting for now as the cabinet is full but still love matryoshka related items from banks to buttons. I even have a Russian Doll cocktail shaker.
Most of my collections just sort of happen. Thankfully none of them cost too much as most I've bought from ebay or car-boot sales and some are presents.
What do you collect?
