A little fix for the set-up rows.

Row 1: purl (don’t add any markers in this row, just purl)
Row 2: (Now place your markers like this:) KFB, place marker, KFB, k3 (3, 5, 5, 5) KFB, place marker, KFB, k22 (22, 24, 26, 26), KFB, place marker, KFB, k3 (3, 5, 5, 5), KFB

And that fixes the set-up rows.

Work front straight (WFS) / work back straight (WBS) just means not to do any increases or decreases…just knit either the front or the back (or both, in some cases.)

From Fitted Knits:

Worked in a vibrantly colored thick yarn, this tee is just the thing to layer over a blouse or a simple long-sleeved tee.  Or in warmer seasons, wear it alone to show a little skin."
