Hi pfflyer, (I wonder how many of the younger gals know what pfflyers were? :?: ) I do!
Well, I looked all over KnitPicks and couldn't find the pattern. I then sent an e-mail to the designer, so hopefully I'll hear something from her. I did enjoy looking at KnitPicks though. They have some beautiful patterns. They have about 145 free patterns and something like 34 pages of $1.99 patterns. As far as I could tell every thing looked to be downloadable. I also Googled "mitered knitting pattern" or something similar and although there were a number of hits, the only one I saw that resembled your stitch was the Knitting at Knoons mitered afghan. I suppose someone who is adept at knitting could transform that free pattern into a vest -- not me!! -- but someone! :lol:
