how do i cast on with multiple colors?
You don't have to. Instructions say "With MC, cast on 40 sts, place center marker, cast on 40 sts – 80 sts." Keep working in the MC for 2 ridges, then you start changing colors.
Ingrid, you don't have to have a login to click on links to Lion Brand. I think. Maybe my computer has the cookies set for them...
