The pattern for this vest was very poorly written with errors and vague instructions. I started over at least six times but since it was a birthday gift for my BFF, Laura, I was persistent and figured it out. There are also other posts on Ravelry that address some of the errors. Anyhow - I was pleased with the end result and she looks fabulous in it! I substituted 3 skeins of Berroco's Remix, a 100% recycled fiber yarn of nylon, cotton, acrylic, silk and linen.
