I found this afghan pattern: http://www.craftown.com/cropat3.htm
I really liked the woven crochet look but knew it had to go on my to-do list when I noticed that the tartan pattern was the one associated with my family name. It was a lot more time consuming weaving the strands through than I had anticipated (I could do about three lines (6 strands) in a one hour TV show -- and since my pattern had 27 lines per tartan pattern, just the weaving was about 40 hours).
But, having done all the work on the filet grid I was committed to this puppy and couldn't change my mind halfway through and go for a lapghan...
Because you fill the gaps you have in a normal crochet afghan it is wonderfully warm and cozy, but not at heavy or bulky -- you don't catch your fingers in the holes either -- it feels like a woven blanket.
