You know, I’m not 100% sure those seams are flat felled, as some are saying. It could also be top stitching to tame the seam allowances. It would definitely be easier to do it that way.

Draw the seamlines. Add grailines and names to the new parts. Add notches to help you align the parts during construction. Cut apart. Add seam allowances.

Just to add on the seam allowances, on this picture it look like flat felled or another special finish. Those need a specific seam allowance so plan ahead for that :)

Threadandsprout has a tutorial for this based on her nature dresses! (Unsure how much it costs, but the step by step was helpful for me)

2) on your traced pattern, draw in the lines you want

I bet they are not flat felled. The stitching just gives that impression.

Other folks have mentioned how to modify patterns for colorblocking, but another method if you don't care quite as much where the different seam lines lay is just to sew your different pieces
