I designed this shawl while playing with increases, mesh, and math. It reminds me of the lattice work on the porch my dad built when I was a young girl.
The yarn I used has since been discontinued. It was a DK weight, and I used a US7 (4.5mm) needle. Yardage (700 - 850) is an estimate. Sorry I can't be more specific, like I said, it was a "what happens when" project. It would look great with coordinating scraps, as it's comprised of 3 repeating sections (garter, stockinette, and lace mesh) and yardage will vary based on how many repeats of the sections you decide to complete.
I would categorize it as an advanced/adventurous beginner pattern, the sections are not difficult, but you do need to pay attention from time to time, and many of us loose our rhythm when working mesh.
My fee is a nominal because I am not comfortable charging much for a design I created while "playing around" but I did have it edited and test knit by others.
I believe in paying designers for their hard work and monetary investment in their designs - yarn, editing services, and printing/design services are not free. Many designs are much, much, more elaborate and required much more effort on the designer's part. Please respect designer's pricing decisions as each pattern you purchase is someone's intellectual property, just like a book or sheet music.
