Pattern recommendations for UL down quilt/ sleeping bag pls

[SS23]

I've posted a Wanted To buy in the market place though don't have high hopes, so am also looking into patterns/ instructions for making my own. I'm alright on my sewing machine and making things. There's a lot of youtube vids and websites with UL quilt/ sleeping bag patterns, so I'd like to get recommendations from people who have actually made them or know the designer/ maker has a good reputation.
Thanks in advance!
