No pattern necessary.
I cut one rectangle 14cm x 75cm from dark blue.
And another 20cm x 110cm from the print fabric.
Sew seams at the back in the dark blue and the print fabrics.
Gather the print onto the plain fabric and stitch.
Make a 3.5cm casing at the top of the plain section leaving an opening for the elastic.
Sew a narrow hem at the bottom.
Thread 50cm of 2.5cm wide elastic through the casing and zigzag the ends together.
Sew the opening of the casing closed.
For the headband I used a rectagle 10cm x 52cm.
Sew the short ends together to form a circle.
Fold or iron 1cm along both long edges.
Sew the ends together of a 50cm length of 2.5cm wide elastic.
Slip the elastic into the headband.
Hold folded/ironed edges together, stitch as close to the edge as possible.
