I just moved up to San Francisco, and I hear it gets a bit cold. I had some extra yarn and decided I'd make my girlfriend a warm gift. It's super easy to make so I decided to share with you guys the pattern of how to make a nice simple button infinity scarf.
-DC = Double Crochet
-Ch = Chain
-Rnd = Round
Ch 102 (or to desired length)
Rnd 1: Skip first two ch's, dc 100, turn (100)
Rnd 2: ch 2, skip ch's, in back stitches only dc 100, turn (100)
Rnd 3: Repeat
Rnd 4: Repeat
Rnd 5: Repeat
Cut and tie off, sew in ends. Sew on two (or more) 1 1/4" buttons to one side of the scarf. The buttons should fit perfectly between the dc bars while still holding in securely.
That's it!! See how easy that is? Took me about an hour to finish and about one whole ball of the yarn.
