I fully expect it is gorgeous and I'll absolutely agree when you post a photo!
It sounds absolutely lovely. Good luck with getting your pattern finalized, it sounds like a lot of effort but worth it. I'd consider volunteering as a test knitter but I'm certain it's way beyond my skill level, get someone who knows what they're doing.
Thanks for adding the info for making larger sizes, it's so frustrating not to find them for myself or someone else. You're wonderful to think of us.
That made me think of Shandeh at Bernat, we both are a bit larger. I wonder if they'd be interested in it. She might be able to tell you how to get the process started too.
