I have that magazine and tried the Pattern 3 (Dotted Block Pattern) over 25 stitches (a multiple of 7+4). All of the times you work with the yarn either to the front or to the back make the floats end up on the back side of the fabric, the same is true here.
Row 5 With F, k1,*p2, sl 2, wyif, k1, sl 2, wyif; repeat
this being a purl row, wyif…I am getting a line of yarn across the two slipped stitches…on the Right Side of my sweater
do I flip the yarn to the front…do the K1 and then flip it back
Since this is the purl row and you hold the yarn to the front for the slipped stitches they end up on the back not the front of the sweater.
k1,*p2, sl 2, wyif, k1, sl 2, wyif;
To explain where the yarn is over the whole row… with the yarn in back knit the first stitch, then bring the yarn to the front and begin at the *, P2, sl 2 wyif (there is no comma between sl2 and wyif). You purl those 2 with the yarn in front and leave it in front to slip the 2 stitches. Then put it in back to K the 1 stitch (this creates a purl bump in the center of each of the squares you’re making). Sl 2 wyif (again no comma), so you move the yarn to the front after the lone knit stitch, so you can slip the 2 stitches. Then you go back to the * and repeat so you will begin there with the yarn in front again for the P2. After all the repeats you need you will end with P2 and knit the last stitch.
BTW you gave very good directions for finding the place where you are in the pattern. Very helpful. I really am fascinated by the little top you are making. It has so much going on that it really looks like fun. I thought of making it too, but kind of expensive to get all the yarn. Of course, it wouldn’t be for me, so I would have to give it away too. LOL
