I loved the way the Babette afghan had a variety of size granny squares all put together. I didn't feel like doing the square pattern that was suggested though. I just did a basic granny square instead. I used black to sc the squares together. I like how it makes it look like the black is a border around the squares. I sent this to my step-son (18) in Connecticut for Christmas. This bad boy took 95% of my guy colored yarn...guess that means I just have to go and buy some more.
When I saw this on Knitty Gritty I knew I would be making one! The pattern calls for it to be knit, but I don't like to weave in color change ends in knitting. I always feel like they will work themselves back out. So, I decided to crochet it instead. I did it in smaller sections and then whip stitched them together. I thought all those bobbins for the color changes would get too tangled if I did it all at once. I can see the joins when I look at it, but hopefully when he wears it it won't be too obvious.
The pattern called for it to be knit from end to end, but I thought the letters would look better if I crocheted it from side to side.
I used this knit pattern for the caution scarf:
