DIY down hoody

High all, new to the site and to DIY. I have been having a hard time finding some kind of pattern to make a down hoody (something along the lines of a ghost whisperer but warmer). Just got into hammock hiking which was a major gear shift so DIY made sense. I had lots of covid related time to make (and use) a hammock, winter tarp, winter underquilt, shoulder season underquilt and finally a shoulder season top quilt. Really surprised how far my measly skills have come along. My wife is a ringer though and stands ready in the wings (but is called on less and less with every project).

frankly, making things based essentially on a rectangle (more or less) has been relatively easy to create but clothing is something else completely. but, hey, there is still a few yards of 49argon from Dutchgear and several ounces of quality down left over...I'd really like to try my hand at a jacket.

Any suggestions on how to get started?
