Background: I'm a beginner, I have sewed few shorts with elastic waistbands, a few tops and some other small projects.
This is my first time sewing a zipper and I don't think that this pattern is a good starting point as the instructions (text and image) are not very clear and precise. There are usually multiple sewing step in one bullet point. The fact that there is no video, and the one that they point to (tutorial video for their chino pant) does not use the exact same technique (not only for the zipper but for the other parts too). So sometimes it is quite confusing.
In general, if you are like me, you can get by by geeking around tutorials on youtube etc, but I have seen better pattern instructions.
Otherwise, I guess it is a good pattern.
