Scarves from Sarah

So my twin sister, Sarah found this really simple way to create scarves from t-shirts that require NO sewing so I asked her to share the process on here with the rest of you.  The above video is how to make an infinity scarf.  The video below is a fancier version of the infinity scarf.
Materials you will need:
Scissors
1 t-shirt
A pin (optional)

 These scarves are completely recycled from old t-shirts and only take about a minute to make.  This could be a great, cheap, Christmas gift for loved ones.  Who doesn't love scarves?
