Pattern reads: K2. *yfwd. Sl1. K2tog. psso. yfwd. K3. Repeat from *. How can you do last yfwd then K3?

its telling you what postion your yarn should be in is all wheather its to the front or back of your needle this case its bring yarn to the forward or front potion then continue to know the k 3. when you knit the sl1 and continued at some point your yarn landed in the back now bring it forward the yarn forward will end up making like a button hold or loop in your design on the next row cause my guess is your going to either knit or purl in that later. man i hope i didnt confuse you
