My FiancÚ and I are both Doctor Who fans, so I made my wedding garter as a surprise for him with DW themed charms, tardis-blue ribbon and 4's striped scarf. I thought it would be nice to have something fun and colorful in contrast to my white dress instead of the traditional lacy type. The scarf part was fun to make, to get the right colors I had to knit it out of embroidery thread. XD
UPDATE: I ended up not using the crochet one after all, I made a matching DW themed throwing garter instead.
You can see the rest of the charms in this picture, I hadn't finished adding them all:

Since I want to keep this one, I crocheted another garter to throw, but it's much more traditional. fav.me/d6aymg8
