Cassidy's pattern is available again :). They figured out what the snag was on Ravelry. Yeah.
This is the one I used to make my version of it. I did a seed stitch at the top of the collar, along the edges and it looks like I did a a little something different on the lower edge. All the hard stuff like number of stitches and when and where to decrease I leave to the designer (you know the hard stuff) :)
