For a while I have searched for a comfortable, inexpensive, and unique infinity scarf, but have been unable to find one. I decided to make my own using two thrifted (semi-damaged) scarves. It makes for a cool mix of patterns and/or colors and it was very easy and inexpensive to make.
Note: The two scarves you pick should be similar material so that the scarf hangs well. You can also buy two different fabrics instead of scarves.
Step 1: What you need
A Sewing machine
2 scarves you want to transform or 1 yard each of two different fabrics (1 yard is being conservative. You can buy less depending upon how wide you want your scarf to be)
Appropriately colored thread
Step 2: Cut
Cut off any tassels or trims attached to the original two scarves.
Step 3: Cut some more
Cut each scarf into a rectangle that is approximately 35" long and has the width of the smaller of your two scarves (my width was 22"). Try to keep any of the original finishing on your scarves so you have less sewing to do later.
Step 4: Sew
Sew together the ends of your two scarves on both sides.
Step 5: Finish
Finish off any parts that may fray.
