Hello, there are lots of different ways to cut out patterns.
You can certainly trace your pieces and then cut them out. Your pieces will be really accurate that way.
One of the easiest ways to transfer stitching lines is to take a needle and poke holes into the stitching line. Then take a water soluble pen and mark the dots.
I like to trace the original pattern pieces onto freezer paper. You can iron the paper onto your fabric and cut around that. This way your not damaging your original pattern when you poke holes into it. But you’re using a digital pattern so you can print the pieces as many times as you like.
If you ask 6 different sewers how to do something, you’ll get 7 different answers!
Have fun. This is a cute pattern to make up.
