Here is all the preparation that Janet and her sister Helen had done for us. A choice of four colours which was fortunate as there were only four members present as well as one of Sandi's friends.
There are only three pieces required to make a turban: the single piece of fabric, one small piece of fabric for the tab, and a piece of ribbon.
First step: sew the two darts using a 6mm seam.
Then join the two long edges and sew with a 1.5cm seam to about 2cm from the folded edge, seen here marked with a pin.
Shown below is that seam sewn.
Sew the longer edges of the tab together with a 6mm seam then turn right side out. Sew one short edge of the tab to the opening of the turban.
Slot the tab end inside the turban and thread the ribbon through the two channels of the long seam anchoring it around the tab, making sure to attach safety pins or bodkins at the end of the ribbon to enable you to thread. Seen here are the safety pins peeking out of the channels and the ribbon pulled tight.
