Cut the fabric: If you’re using a tea towel, I recommend folding it in half (the short way, not the long way). If you are using fabric by the yard, I also recommend folding it so that you have two layers. Mark a rectangle of 23″ x 31″. If you’re using a kitchen towel you might like to use one of the finished sides so you don’t have to secure it with a zig-zag stitch or serger.
Keep the cut sides from fraying: Using a serger or zig-zag stitch, finish all cut sides.
Hem one short side (if using fabric by the yard): If you’re using fabric by the yard, fold over the fabric once or twice and sew the hem.
Sew the 2 open sides together: You might like to pin your folded fabric in place to prevent shifting. Then, using a .5″ seam allowance, sew one short side and the long side together with a straight stitch. NOTE: only sew the long side to about 2.5″ from the top. Leave the rest open.
Press the seam: Either use your fingers or a hot iron, press the seam on the long side open.
Secure this seam: Sew a few times back and forth perpendicular to the seam to secure it.
Sew the remaining 2.5″ inches: Use a straight stitch to sew the two open pieces in place.
Pin the tunnel for the drawstring: Make sure you still have the right sides facing in fold the top of the bread bag over about 1.25″ to create the tunnel. I recommend pinning it in place
Sew the tunnel: I recommend using the free arm of your sewing machine for the next step: sew the tunnel in place with a straight stitch.
Guide the drawstring through the tunnel: Put a safety pin through one end of your cord and move it all the way through the tunnel. Secure the ends with a knot.How to make your own drawstring: you can use some thick yarn and crochet a long string.
