If you search for shawl/wrap patterns on Ravelry Wingspan by maylin Tri'Coterie Designs will be among the Top 10 with over 10'000 projects. There are also quite a few variations and adaptaions
of it (as you can see on this Pinterest board).
Some time ago, I received and email from the Designer (maylin from Tricot Treat) with a gift of all her patterns. At the time I was really touched by this gift, because it was so unexpected.
And this morning, I found another receipt email from Ravelry in my inbox - with another pattern gift, her new pattern: a swing knitting version of Wingspan called Rigoles. Again, I am surprised and I honestly think, that it's a lovely, lovely present by a very gifted designer. Thank you so much!
I downloaded it. The pattern is written with much attention to detail, many illustrations and photos, plus there are some diffent versions included.
Unfortunately, I don't have a photo of a finished shawl, but there are some really nice ones on the Ravelry pattern page of Rigoles. I can only show a screenshot of the pattern's thumbnail.
P.S.: Three years ago, when I published the Mixed Wave patterns (cowl and fingerless gloves), I tried to do a wavy (or swingy) version of Wingspan as well. But at that time doing short rows within short rows was a bit to much for me - so I frogged it ... and I haven't tried it since :)
