I took Suzy Ferrer's class on pant slopers. I went through 10 slopers before we were both satisfied with the fit. She has endless patience. I have not much tummy, flat hips, flat bum, dropped bum and not big thighs. I think curvy people are easier to fit. I now have a patterns for slacks and a pattern for jeans. Yes, I just love how these fit. The fabric dictates a lot of the final fit. I do the zipper and pockets. Baste the back seam, and sides, try it on and adjust if needed. Firm fabrics, not much if any, stretch fabrics adjusting is needed.
