If you're making a shirt with a buttoned cuff sleeve, you'll definitely want to check out this tutorial. In this step-by-step demonstration, we'll show you how to do the sleeve placket, which is the opening above the cuff. The sleeve placket is a separate piece used to finish the raw edges of the opening while giving it a professional look. I use a contrasting fabric print to make it easier to see what's done, but you can always use the same fabric as your sleeve for a more subtle look. There are several steps to putting in a placket and some parts are confusing. Hopefully, seeing me do it will take some of the complication away and will make this part of sleeve construction a lot easier and faster.
