The pattern is back up on Ravelry, and I'm working on a glitch in getting the updated version (along with notifications) out to prior purchasers. If you've already made one of these and would like to make it better, all you will need to do (once you receive the update) is to frog the old collar back to the pick-up row, wash the frogged wool to get out the kinks, and re-knit the collar following the new instructions. The new version actually takes slightly less wool than the old, so you shouldn't have to worry about running out. Of course, if you have a leftover skein you could also use that. I really love this design and can't wait for some cool weather so I can enjoy wearing it.
P.S. Reporting back same evening: the brilliant Ravelry folks have solved the glitch and updates have already been sent out.
P.P.S. Frostfern is next up for the same treatment. Stay tuned...
