Ok, the row starts with the (k1, p1) 3 times and then begins the repeat *k1, yo, k4, dec2, k4, yo.
So written out with 2 repeats it would be:
(k1, p1) 3 times, k1, yo, k4, dec2, k4, yo, k1, yo, k4, dec2, k4, yo,
Repeat the underlined portion as often as you need to finish all the sts on the row.
Can you give us a link to the blanket pattern or a pattern name?
