Here are my most worn pieces of 2008. These are not necessarily my favorite patterns, just the garments that I actually wore out my front door the most. It's not so useful sewing up a closet full of things you never put on, so my focus in the last year was really wearable things.
I tracked down how to buy a copy of KnipMode magazine when I saw a line drawing of this shirt. I wear it with jeans to work all the time, and I've got material cut out to make up another version of it. I love the collar and the unique tie front.
BWOF 11-2007-118 Hoodie
Made in a marimekko cotton rib fabric. Sooo comfy. pattern review here
BWOF 06-2008-107 Blouse
Now my go-to button front blouse pattern. I think I have about 5 of this pattern now, and plans to make at least 2 more. It fits me perfectly, which is a small miracle. pattern review here

I made this three times this summer, and I wore this version quite a bit. The fabric is from Fashionista Fabrics.
Self drafted flare skirt pattern
This version is in a black/white tweedy wool and lined in pink silk shantung, made last January. This pattern was just made by closing the darts on my skirt sloper, so it fits my sway back really nicely. It's one of the only wool skirts I really wear often.
And I'll offer an honorable mention to the Stitch Magazine pintuck skirt. I've worn it twice already, and I'm sure it's going to get more wear in the coming year.
