Here is a comparison between the dc, knitted, and sc look. The colors do not show up well in these photos, but you should be able to see the difference in stitches. The original scarf was knitted.
The top one is Stylecraft Special DK Camel in double crochet. The one in the middle is I Love This Yarn Lt. Taupe in knit The bottom one is Knit Picks Brava Sport Almond in single crochet (the one I finished recently).
Here is what I've done so far on this one. Again, the colors in the photo are not really accurate. The grey, for example, is not as blue as in the picture.
I will of course give you an update when it's completed.
Happy crocheting!
