Here's a photo tutorial on how to make a lovely headband. It's pretty easy and looks pretty profesh. Enjoy!
Sorry, my usual photographer was taking a nap.
One piece of oilcloth, 1.75 in. x 18 in.
One package of double fold bias tape
One four-inch piece of 1/2-in. wide elastic
1. Cut two lengths of bias tape to run along the long edges of the oilcloth. Slip the edge of the oilcloth into the bias tape. It should fit snugly in there. Sew the bias tape in place, making sure you're sewing through the top layer of the tape, the oilcloth and the bottom layer of the tape
2. Using a zig-zag stitch, secure the elastic to the raw edge of the oilcloth.
3. Fold in the corners of the band so it makes a taper. Sew in place with a zig-zag stitch.
4. Place the headband around your head and adjust the elastic so it's comfortable. Repeat steps 2 and 3 for the other end of the band.
It's as simple as that. Only took me about 10 minutes total.
