Infinity Scarves

It's a scarf! It's a hood! It's a whole lotta fun!
Basically, you cut a strip of fabric about 33 cm (13 inches) wide. You'll be using the fabric's whole width, selvage to selvage, so you'll end up with a strip of fabric that is 33 cm wide (13 inches) by 140 cm (45 inches) or 150cm (60 inches).
Cut two of these strips in contrasting colours, and decide which will be the main colour.
Pin right sides together, and sew the long edges together, using a wide zigzag stitch. Go slowly, so you don't break your needle on the pins. My seam allowance is .5cm (1/4 inch)
Turn the scarf right side out.
Pin the main colour ends -- right sides together -- matching the side seams as closely as you can. Then, on either side of that seam, pin about 7 cm (3 inches) of the lining fabric right sides together.
Sew together in a continuous seam, taking care not to catch the rest of the lining in the seam (happened to me twice, and I said some bad words).
You'll have joined the main colour together and have just a bit of hand sewing to close up the lining seam.
Eh, voila! A scarf that is both a cowl and a hood. They are very comfortable and warm.
