I'm fairly new to wool too, so far I've only made a pair of shorts. I'm not sure if my material was jersey or interlock, I got both and forgot which color was which.
: I only used 1 layer and they work great for daytime, I've never tried them at night but I'm guessing they'll be too thin. I'm planning to make some 2 layer covers, maily because I like the construction method. I don't have a serger and FOE hates me so I T&T.
I own 1 wool cover by PWP, it's 2 layers of lightly felted "something" and much less bulky than my Windpro covers!
I guess you could try 1 layer and see how it works for you before cutting a bunch of your wool up.
