After seeing this pattern years ago and adding it to my Ravelry queue, I started this project on April 21.
It took 30 pattern repeats and two balls of Crystal Palace Merino Frappe to reach 5-feet. I purchased the yarn years ago intent on making a Spiderweb Capelet from Stitch 'N Bitch Nation. Needless to say, I did not make the capelet.
The positive part of using this yarn is that for a wool yarn, it's quite soft from being merino. The downside is that with it being frappe, it is a pain in the ass to rip. By knitting stitches, the felting process starts. It made ripping back on rows with too many stitches a very annoying experience. And wouldn't you know, that all had to happen half-way through the project, which was not very motivating.
