now look at the scarf : it is made with lots of chains, linked together with regularly spaced double crochet. every start of a new raw makes one piece of fringe. (actually on the picture, you can count the stitches to have exactly the same effect than this one : looks like its 15 chains, and 5 double crochet in between.)
One of my favorite patterns. Infinity scarfs are now my new favorites. Used the exact same yarn - lion brand tweed in "woodlands". My son like it so much he wanted one. Also made it in lion brand tweed - "caramel" too. Have made 4 so far. Friends love it! Takes about 2 hours once you learn the pattern. Easy beginners scarf!
