You will need:
A pair of sharp scissors
About a yard of a nice knit fabric
A good sewing machine with the appropriate needles that won't snag or pull the fabric
A box of pins
About an hour
Things to keep in mind:
-When buying your fabric, choose something that isn't scratchy or rough because this will be lying against your neck
-Buy fabric that is a cotton blend and can just be thrown in the wash to avoid high dry cleaning fees
-Select fabric that has a texture so that when you heat up inside of it, your heat will be trapped in the texture so that it can keep you doubly warm
-You do not have to limit yourself to what the fabric stores sell. You can create your own textiles with some various fabrics and create a patchwork style fabric.
Step 1: Measuring and Cutting
Since I wanted my Möbius scarf to be really wide, I cut my yard straight down the middle from the fold to the selvages. Now I have two 18 in wide sections folded in half. That means that my scarf will be about 8 and 3/8 inches wide when finished.
Now pin one of the selvage ends to the selvage end on the other section, right sides together.
