yup, i scaled it up to just to show it in examples, when working on a piece you just imagine it. and for the curves i go with what feels right too.
there are some rules how to make a curve smoother, for example if the pattern is 1,1,3,2,4,4 - you change it to 1,1,2,3,4,4. however, it always depends on what shape you’re going for (sometimes things have bumps you want to keep). so yeah, in the end, just check the image in preview window at 100% scale and play around to find what looks best.
