Challenge yourself to sew a wonderful fully-lined kick pleat. This is definitely an advanced technique, due to the need to clip into seams and pivot as you sew. If you would like to do it the easier way, just follow the easy version in your instruction booklet.
As always, if you are not confident with a challenging technique, a great way to practice with no fear is to simply make a sample. Cut some scrap fabric and lining using your Back pattern pieces (no need to cut the whole Back out, just the area around the kick pleat).
Please note: these videos are a part of a full tutorial series which will be released over time, which is why only specific numbered videos are available right now.
