I'm so glad I finally finished my crochet hexagon blanket. It took me quite some time: I started on May 20, 2010 (that's right, 2010!) and I finished it some days ago (Feb 19, 2012).
The pattern I used was the Ruby Hexagon Blanket by Nova Seals for novamade. I used different colors of worsted weight yarns I had on hand. Every last row I crocheted in black. The first border was also made in black, whereas the second is made in lime green.
This is how it looked like one week after I started; and another pic of the finished blanket.
