Hallmark christmas ornaments. Everyone in the family gets a new one every year, sometimes more than 1 if there is something that is perfect for them on top of the theme they have gotten since being a baby. All 3 kids had over 50 when they moved out, my mom bought them some as well when they were little.
Blown glass spheres and eggs, husband got me first one when we were dating. He has given me one every year since, never on a birthday, anniversary etc. Just on a random day one is somewhere for me to come across, I have 31 now.
Husband has t-shirts, I believe his goal is one for every day of the year. He just will not admit it.
