Instructions
Lay out the shirt on the cutting mat.
Use the scissors and cut off the sleeves and collar at the seams.
Use the ruler and fabric pencil to mark straight lines along the shoulder area of the shirt and next to each of the arm holes, then cut straight down the side seams The goal is to create two rectangular pieces.
Flip over one piece and fold down the top about ¾ inch. Pin into place.
Use the needle and thread to sew along the bottom of the fold, at the cut portion. You should now have a casing for the drawstring.
Flip over the second piece, fold and sew in the same manner as the first piece.
Place your two pieces together, faces together (right-side in). Pin along the bottom and sides, making sure to start below your casing seam. Seams of ½ inch or ¾ inch are fine.
Use the needle and thread to sew the pieces together, staying straight and in the middle between your pins and the edge of the shirt fabric.
Tie the cord into a small knot around the coil part of the safety pin. Push the safety pin through one side and out the other. Tie a double knot into each end of the cord.
Repeat the cord threading and knot tying for the other side.
Turn your new shirt drawstring backpack inside out and inspect your seams to make sure you didn't miss anything.
