My pattern says yfwd,sl 1,K1,psso,K1,K2tog,yfwd,K1
y question is, after my sl 1, do I bring my working yarn to the back to do the K1 that follows

What is your pattern... is there a link???
Sometimes YFWD means YO ... but in any case, if you are to do a K1... your yarn should be to the back when you work that K1.
