Below is what I need to do for my mittens. when I get to the part for the thumb gusset I am not sure what I should be doing.
I know how to M1 but I get confused where it says slip marker. Hope someone can explain it to a not so knowledgeable knitter.
Row 1 (RS): K12 (14, 17, 20); place marker; M1, k1, M1; place marker; k12 (14, 17, 20).
Row 2 and all WS Rows:Purl.
Row 3:K to marker, slip marker, M1, k to last st before 2ndmarker, M1, slip marker, k to end.
Rep Rows 2 and 3 until there are 9 (11, 13, 15) sts between markers.
