It's absolutely gorgeous! Thanks so much for sharing this!
The one I'm doing to test the extensions is out of an inexpensive(cheap), cotton slub yarn, about a size 10 and using size 2 needles so it will look alot smaller than yours. I wanted to make sure that the extensions were right before I do one in a worsted weight or spent alot of bucks on a nicer yarn. It's looking okay, can't really tell with it being a bag right now.
