The finished products - one skein of Katia Ondas produced two scarves from different patterns, each about 64" in length:
Scarf #1 with four stitches cast on:
Scarf #2, done lengthwise:
Worked lengthwise for a slightly less flouncy look. Cast on 86 stitches, worked three rows, bound off on the fourth row using the larger needle. The bound off seam does show a bit, but not enough to be bothersome. IMPORTANT: rewind this yarn prior to using. There was an ugly midskein join to work around.
Notice the difference in the looks of the two? Each one took 16.5 yards (1/2 skein) of Ondas, which is a tape yarn that you knit along the edge, unfurling the pre-made ruffling fabric as you go. Knitting magic for $12.95 (Cdn) for two.
