Hi there! It may take some time to get used to but I’m sure you’ll pick it up quickly. The trick is just making sure you’re cutting out the right size. You can see me working with an easy example of new commercial pattern in our tutorial Simplicity mini dress. We start at the very beginning from reading the envelope to doing all the prep work so I hope it’ll give you more of an idea. You can see it at this link: https://www.professorpincushion.com/professorpincushion/simplicity-pattern-2147-mini-dress/
You can do it!
