This instructable is for the Etsy SewUseful contest...
Step 1: Materials
1/2 yard 45" wide cotton for outer layer
I chose a cute banana-print cotton; any decorative or fashion fabric will do, but it should be woven (not a stretchy knit).
1/2 yard lining
This is the part of the scarf that will be against your skin, so choose something warm and comfortable. Softer felts, flannels or fleeces are all good options.
These can be lace, eyelet tape, or whatever else you prefer. If you plan to adorn all the edges, you will need 4 1/2 yards of trim for a 68" scarf. To decorate only the short edges, 1/2 to 3/4 of a yard will do; vertical accents will require 2 yards of trim each, and horizontal accents will only require 6 inches of trim each.
D-ring and nylon webbing
These are for creating a decorative accent and/or ring to clip your keys to. You can substitute the nylon webbing (only a few inches are needed) with a piece of matching or contrasting fabric.
This is for constructing a pen or pencil sleeve. You only need a few inches; choose a color that complements your lining and fashion fabrics, as it will be visible.
Bias square, measuring tape, or ruler
Chalk or marking pencil
This project can sew by hand with a needle and thread, but a machine will make it much faster and easier.
