I'm halfway done with my blanket. Four skeins out of the 8 I had for the main color are gone and 72 hexagons are done (that is 18 hexagons per main color).
The pattern is from a tutorial by Attic24 (hexagon how-to).
The yarn is Kambgarn - a sport weight merino yarn, processed (dyed? packaged?) in Iceland. They have great colors in this yarn.
The hook is 4.5 mm (US 7). The one I'm using is from Susan Bates and it has a nice wooden handle on an aluminum hook.
I have about 10 colors, plus the main color. It is so much fun to always have different color combination. I don't select the colors randomly so it is a bit of a puzzle to select a color without repeating the same color too much at any one point. At the same time I don't have to worry too much about what all the other hexagons are, only the ones closest to the one I'm doing at that moment. So easy-piecy lemon-squeesy (as my 7 year old would put it - the one in the picture).
p.s. the blanket has been blogged before, here and here.
