My daughters are 33 and 29, plus we now have a son-in-law, and I still do stockings for everyone. The ones we use now I made in the quilt-as-you-go fashion with strips from my Christmas fabric stash and each is unique. Actually, the girls chose the fabrics for each one, combinations to fit the person it was intended for.
Each year I put in candies, small gifts or toys, and gift cards. It's fun to think how those items have changed too. I used to give simple candy canes and chocolates and small toys. Now I put in things like gourmet chocolates and gift cards to Starbucks. I also try to add something useful. One year I gave everyone a small hand-cranked flashlight and another year everyone got a tire pressure gauge. But I still include something fun, a toy or tiny game. This year my youngest daughter got jacks and my husband got a tiny wind-up fishing game.
Also, as my girls have grown up, they've started adding to the stockings themselves. I usually don't put things in my own stocking, but boy they do. I get candy and gift cards too now, just like everyone else. This year my husband even bought stocking candy for the first time ever! The stockings are usually so full they're overflowing.
This is one of our most fun traditions and I will continue for as long as I can. When grandkids come along, they'll get stockings too, quilted of course.
