A couple of things I always try to fit in are handmade gift bags and tags. They're a whole 'nother thing I really enjoy. The making hasn't started yet, so for now, I thought I'd repost two of my favorites, both my own tutorials.
First, the Trim-Tied Gift Bag, which is handy, with the ribbon attached. My favorite is made with a linen-blend, as show below, but the tutorial tells how to make a lined version using quilter's cotton as well.

As for tags, I make mine with quilted scraps. Born in desperation one Christmas Eve, they're fun to make, and use up those festive Christmasy bits from your other projects.

So what's your favorite Christmas make, or what's on your list to do? And though I have a collection of tried-and-true gift bag tutorials, I'm always happy to learn of more.
