I'm just trying to duplicate the shape/size, not necessarily the stitch. For example, I found some super cool "loafer" style slippers and want to replicate the shape of the slipper but don't care what stitch it used. How would I go about figuring out the schmatics of it?
The sweater pattern is easy - there's a drawing with measurements and it's basically square, with notches for the armhole. So you would knit pieces the same size and BO about an inch or 2 at the underarm on both the fronts and back. Then sew the pieces together.
