You slip the first stitch of every row, purl wise. This creates a really nice edge for the sweater. However, if you miss slipping that stitch just once, it shows up and looks so bad. I did that a couple of times and the edge looked awful so I got the great idea of adding a single crochet edge on the sweater and it looks great! Nice and finished and even.
Love this pattern. No seams, top down. If you want to do a big button on the sweater, make the buttonhole a little larger than just the one yo that the pattern calls for.
I introduced a little color by doing knit one beige, knit one blue, etc. Then the second row would be to knit blue of beige and knit beige over blue, etc. For knitted flat garter stitch, hold the blue color in your left hand and it will look stranded. For the circular sleeves, you knit one row and then purl the next row to make garter stitch, so the color knitting is a little different on the purl side.
Went up to a #7 needle for the two-color knitting, since it was tighter.
