I haven't picked up a crochet hook in years but this looked interesting, so I gave it a go. The design is intended for a bulky weight Thick and Thin by Lion Brand and a size 9mm/N hook.
Having neither on hand, I opted to test the pattern using a worsted weight ragg wool and a size 7mm/K hook.
Once the Foundation Row is set up the pattern is a simple repeat of Row 1 for 60 inches or until your yarn holds out, or until you decide to quit! Leave enough of a tail to whip stitch the two ends together... this is the step that makes it the circular Infinity scarf.
The pattern is intended to have a smooth edge at the sides, which is accomplished by the dc in the last space (ch 3 turning space). If you like the scalloped edge simply ignore that bit, and after the last V in the row, chain 3, turn (or turn, chain 3 if you prefer) and begin the next row. The scallops lay flat without curling and gives the scarf a nice finished edge.
