Learn how to true your seams. Seams need to be trued after you have made any amendments to a pattern, be it an already existing pattern or a block/sloper that you are drafting from.
You need to check the stitching lines of the patterns to check that the seams are the same length, and you don’t have any discrepancy when sewing these together. You also need to check that all joining seams have smooth curves, and blend together properly. The joins should be flat (sometimes ‘right angles’), so that you don’t have any dips or peaks at the seam join when sewing the garment together.
