I had some personalized koozies made a few years ago and just finished using those up (for the adults). I buy a lot of stuff from Dollar Tree. Tops, toy compasses, sports balls, plastic animal figures, etc. I have found some NICE handmade pieces in some caches. If I come across something really cool and on clearance, like our Family Dollar was going out of business and I bought an entire box of rocks with uplifting words etched into each one (dream, believe, etc), then I grab those. I keep a bag in the car at all times since I never know when I will need some swag.
