How to Sew a Mock Turtleneck Inside a Sweatshirt
- 1). Choose a sweater, new or used, for your project. Choose a fabric you want for the mock turtleneck.
- 2). Wash your sweater (if it's new) and fabric in a regular cycle. Dry it at the highest setting. This will ensure maximum shrinkage and prevent the fabrics from shrinking later. This keeps the stitches from pulling the fabric.
- 3). Draw a pattern for your mock turtleneck. Place a sheet of paper on a flat surface. Measure the circumference of the base of your neck with the measuring tape. You may require someone to assist you. Apply the measurement to the ruler and draw it as a horizontal line on the page. Determine the height of the mock turtleneck you would like and double that height on the paper by drawing a vertical line from one end of the horizontal line. Draw the remaining lines with the ruler. The pattern should look like a rectangle. Cut the rectangle, leaving a half of an inch on all sides. This will give you extra fabric if you need to adjust the fabric with the sweater's collar a bit more.
- 4). Pin the fabric to the paper pattern. Cut along the edge of the paper. Remove the pins and paper. Fold the fabric in half, short sides together, right sides out.
- 5). Turn the sweater inside out (wrong side out). Lay it on a flat surface with the front facing up. Make certain the shoulder, arms and body seams are matching. Fold the already folded fabric in half, long sides together, giving you the center of your mock turtleneck. Line the center fold edges at the bottom seam of the collar. Adjust the fabric edges to fall a half of an inch. Pin the fabric evenly along the collar seam. You want the fabric seam at the center-back of the sweater.
- 6). Starting at the fabric back, sew fabric and sweater together at the sweater's collar seam, excess fabric facing outside (the "wrong" side of the sweater). Continue sewing along the sweater collar seam.
- 7). Cut away all but one tenth of an inch of the fabric edges. Hem remaining fabric. Remove pins, and turn sweater right side out.
