So I'm completely baffled when it comes to baffles. I am starting a DIY UQ project because I received 7oz of 900 fill down to play with. I'm going to make a 3/4 UQ to hopefully make it rated to around 25-30f. I'm going to order some 1.1 ripstop from DIYgearsupply but before I do all this I want to understand baffles. I can sew and have had quite a bit of practice.
Does anyone have a link to some diagrams? Also, I noticed uses "Dual Differential Cut Radial Baffle" and I have close to no idea what that means. Can some of the DIY veterans step up and help a novice out?

Thanks in advance.
