Sewing DIY - Grey Pullover to Jacket (Wardrobe refashion)
Mark the center of the shirt where to be cut off, and cut as marked.
Luckly no need to reduce or lengthen this zipper, in this instance. If the zipper was short I would match the bottom of zipper and the bottom of shirt and sew up. and I would fold in the edge of shirt remainder over the top of zipper and sew. If the zipper was long I would cut the top of zipper as needed.
Because the both the shirt fabic and the fabric attached to the zipper together would be too thick to overlocked stitches using home overlocker machine that I have, so overlocked stitch's done for each fabric.
Place the edge of fabric attached to zipper on the shirt edge with the right sides facing in. Pin and sew along the longer sides, sewing with 0.25 inches seam allowance.
Done ~ Happy sewing😉
