DIY Racerback Tank Top - Materials



Step 1: Pin and cut the pattern

With the jersey fabric folded in half, pin the center front pattern to the fold line, and along the sides. Do the same for the back pattern. Using fabric scissors, cut out the pattern. Once they are cut, remove the pins from the front and back.

Step 2: Sew the sides and straps

With both front and back facing each other, pin the sides and shoulders.  Sew the sides and shoulders using a zigzag stitch on the half inch seam allowance using a ball point needle.  When finished, trim the edges.

Step 3: Finish the outer edges

Turn the tank top right side out.  Make 1/4 inch snips along the front and back neckline and armholes.  Fold the fabric over a 1/2 inch pin and stitch along the armholes and neckline for the front and back.  Trim off the seam allowance on the inside.

Step 4: Make the bias tape

The bias lies at a 45 degree angle between the selvage and the width of the fabric.  Measure and cut one 2 inch by 24 inch strip and two 2″ by 30″ strips. Insert the strips into the bias tape maker using the seam ripper to help guide it through. Iron the fabric as it’s coming out of the bias tape maker.  Continue this until you’ve reached the end of the strip.

Step 5: Sew the bias tape

Fold the tape over along the edge and pin.  Once you’ve reached the end, leave a half inch seam allowance and stitch the two sides together.  Do this for both the armholes and neckline.  Last iron the bias tape once it’s finished.

Step 6: Hem the bottom

Fold the hem over 1″ on the inside, pin, and stitch.  Do this on both sides.  Iron the hem for a polished finish, and your tank top is now complete.
