My parents still have stockings for me and my siblings that are displayed every year. They have also added a stocking for every spouse and grand child. I'm one of five kids, four of us are married, and there are three, soon to be four, grandkids- so their staircase will have 13 stockings this year! They will need more stairs soon.
Luckily they just have the most basic red and white stockings that they write the name on in glitter- not fancy but easy to add another stocking as needed.
Is your stocking still up at your parents house?
