It was seen on a British TV show and is a lovely design. A late friend was working on this same shawlette, in these same colors. She used Plucky Yarns. It would be a shame to leave the project unfinished
Update: I've learned that the pattern is "Avant l'orage", which translates as Before The Storm. It's a slip-stitch pattern, available on Ravelry in both French and English.
