Oops!
ktmama, what adjustments did you make to the pattern? This looks like something I might want to try. I'm new at sewing too so any tips would be helpful!
So sorry, lost my sub to this thread - happens to me alllll the time

Anway, I pretty much just customized them to her by measuring her around the waist, the thighs and the rise (from the top of her little butt crack between her legs to just below her belly button). I used some old fleece and some old receiving blankets for the flannel and went from there. The biggest challenge was actually getting the elastic the right length and the leg openings large enough to bunch up with elastic while at the same time leaving enough for the casing.
Don't worry about being new at sewing - these undies were actually the very first thing I ever sewed. I just made my pattern on plain paper and I'm still using that (modified) pattern. Over time, the pattern has gotten more and more trim and not as balloony like it looks in the photo). The other thing I love is that the microfleece is holding it's color and not pilling really at all. PM me if you need some specific advice. Good luck
