Welcome to this fourth part of the Zinnia Sewalong. In this post we are going to start sewing, yay!  Some of the fundamentals we’ll be covering include seam allowances, button plackets (version 1), stitch length and width, pressing a seam, and staystitching. We will also explain how to use fusible interfacing, sew a basic seam, and finally how to do gathering and pleats.
