@ajvician – I don’t blame you for feeling frustrated. When you are sewing garments a well-formed placket can make all the difference in how professional looking your garment is.
I have found several tutorials and videos on the Internet that have helped me to be a better seamstress. They usually point out several professional tips and tools that can be very helpful, too.
I am a visual learner and the videos I have found have helped me the most, but I do like some of the tips extra tips I have read in the written tutorials, so don’t pass those up.
