This was an interesting and, for me, a challenging project: each ruffle is knitted on top of the previous ruffle. The last row of stitches of the previous ruffle are knit together with the next ruffle that has been formed...and so on till one side of the scarf is finished. After the second half is finished, the halves are joined together.
The yarn is Jojoland Melody Superwash in 100% wool in colorway "Lilac Rose." The pattern is "Butterflies Are Free" from Lace One-Skein Wonders edited by Judith Durant (Storey Publishing, 2013, ISBN: 978-1612120584).
The pattern calls for 700 yards of yarn, but I didn't have that much in my stash. After a bit of measuring and weighing I made some adjustments to accommodate the amount of yarn I did have. Each ruffle is supposed to have 3 repeats of the charted pattern, but I did only 2 repeats. Each side is supposed to have 9 ruffles, but I only have 8 ruffles per side. With these changes I did not run out of yarn, and I think the final result looks fine.
