As for the fit, I made the crotch curve a bit deeper, because I was getting the "smile" in the back of the previous pair. It wasn't obvious to me before... I thought those wrinkles were there because they were loose-fit pants. After reading "Fit for Real People" and "Pants for Real People" (now my bibles for garment fit/alterations), I was able to recognize the problem. I think my new Bella pants fit me much better than the first pair!
I used polyester moleskin I got at a closing sale of a local Joann (re-opened with bigger & better selection across the street---Yay!!)----$5 for the whole bolt! It has stretch and the suede-yside, which I love...I already made a new skirt from the same fabric :)
