Make your own onestringbag

Step 3 Insert the draw string

Take one of these pieces of fabric.

You may need to consider your fabric now and decide if you need an extra fold to protect raw edges from fraying.

For the draw-string, cut a piece of string the 16cm longer than this long edge.

Take the long edge of the fabric and fold down about 3cm, tucking the start of the string inside the fold, using a pin to hold it in place.

If you like you can prepare the other pieces in this way to speed production.
You do not need to pin down the fabric all the way as it will be very easy to hold the string inside the fold as you sew with a sewing machine.
