I have little collections of random things but my main collection hobby is glass pumpkins. I only collect ones that are actually done by a glass blowing artist, I pick them up at art fairs and shows, so they are all unique and interesting.
Sewing is my biggest hobby though. I'll sew just about anything. I also do hand embroidery - I work on my projects when I'm in the car during trips, takes me years to complete anything!
