So, I'm looking to make a fully featured 0° bag, and just had a few questions. The basic construction I think I have down, and have enough design skill to execute, but there are just a few details I was wondering if anyone knew of any patterns/resources for:
1) V Block Baffles – The design I'm looking to do would require a V Block or Side Block baffle. I'm having trouble visualizing how this could get sewn in
2) Hood – I've never done a hood!
3) Draft Tube – Same as the hood, never bothered, but for this bag it's probably necessary
Normally I'd forego the hood, and maybe the draft tube, but the bag is for my partner, so most of the comforts are non-negotiable (plus it'd be a fun construction challenge!).
Thanks for any help! I'm super new to the site, so I apologize in advance if any of this has been covered
