Question on The Scrunchable Scarf

[KathyinCali]

Hello All and Happy Friday!

For the scrunchable scarf the pattern says to cast on in multiples of three with odd number of stitches then 2 more stitches for a selvage...What does that mean? Do Knit those two stitches at the beginning and end of each row? What happens to it at the end (as in selvage), do the get taken off at the end? Help - I'm having a brain freeze
