I have a basic dress pattern that I made this way, it’s basically my body shape in a pattern. It’s traced from brown paper onto cardboard.
I know the basics about pattern making but the patterns I make myself, based upon my own measurements, are never perfect because they are 2D, not 3D. I draw my own pattern block based on my measurements onto tracing paper, compare this to my cardboard body shape and make adjustments on the tracing paper.
Then I sometimes trace details from commercial patterns, for example a neckline or a certain sleeve shape, sometimes I draw them myself. My sewing teacher is actually not extremely happy about my way of doing things because I’m not following The Rules of our method of patternmaking, but this gives me the best/fastest results. I really don’t have time to make muslins for every new design. I can only do the basics, skirts, dresses, pants, collars. I don’t do complex tailored designs.
I actually didn’t know people cut into commercial patterns, aren’t those usually on super thin paper? I thought everyone traced them, why else do all fabric stores have so many rolls in stock?
