The Simple Single Crochet Infinity Scarf is the ultimate beginner scarf, because it uses one of the first stitches you (most likely) learned. It works up fast because of the super bulky yarn, and the finished texture is awesome.
THE PATTERN
To begin: Ch 91.
Row 1: SC in 2nd chain from hook. SC across. Bring ends together, being careful not to twist the first row. Join with a slip stitch to the first SC of the row. Do not chain.
(You can also do a chainless foundation stitch (FSC) for the first row of 90 SC. If you don’t know how to do this, check out this tutorial. It will change your life. Be sure to join the FSC, and don’t twist it in the meantime.)
Round 2 (We will now work in rounds): SC in first St of previous row, and SC around.
Rounds 3-13 (or until scarf is about 7″ wide): SC around.
Slip Stitch into the next 3 stitches to smooth out the row, then fasten off and weave in ends.
