If the items in your closet are getting worn out, do not throw them out. Instead use a few sewing techniques to create a new neckline. A round neckline can be turned into a V-neck in a few steps. The improved item will be a welcomed change to any wardrobe. Additionally, the project isn't expensive to complete, which will benefit any clothing budget. Grab old T-shirts or dresses from the closet or ask for donations. In no time, their necklines will be revamped into V-necks.
Turn your garment inside out. Grab your seam ripper and rip the seams of the front neckline. Start at the shoulder seams on either side and rip the front seam all the way around to the other shoulder seam. When you are done, remove all of the little pieces of thread from neckline. Find the centre of the front neckline and cut the neckline into two pieces. They should still be attached to the shirt.
Lay your garment flat on your work surface front side up and inside out. Measure a V from the shoulder seams down to a point on the front of the garment. Mark the line with the sewing chalk. Cut out the V.
Fold the edges of the v-neck over about 1/4-inch. Pin the two pieces down the edges of the V to cover the rough edges of the V. You will have to pull tightly to stretch the material all the way down the V. Do not pin down the point. Thread the needle and sew starting at the shoulder seam. Sew 1/2-inch above the point of the V and stop.
Sew the longer of the two pieces down to the point of the V. Then, sew the shorter piece over the longer one completing the V. You may notice the shorter piece is not well hidden if you have a deep V. If so, you need to thread your needle so you can sew the edge of the shorter piece behind the longer one. Turn the garment right side out. Start at the bottom of the V and send the needle through the front of the smaller piece. Send the needle through the longer piece. However, do not send the needle through both layers, just the back layer so the stitching isn't visible. Continue sewing the stitch to the top of the shorter piece.
Turn the garment inside out and press the seam down. Lay it flat and iron over it.
Set your sewing machine to a zigzag stitch. Add the presser foot and needle plate. They should be wide enough to give the needle room to make the stitches. You want the edges of the zigzag stitch to come as close as they can to the edge of the seam. The stitch will hold the edges of the seam in place so it cannot fray or curl. Try practicing on the scrap piece of fabric you cut from the item before starting on the real thing.
The necklines can also be decorated with beads or iron on transfers.
