There are a few quirky things about this pattern. The first: Your foundation chain has a bunch of beads in it. Maybe you're not used to that, but it's OK; you can still crochet into those stitches, even though they have beads stuck in them. In fact, that's exactly what you're going to do. Work into every stitch, whether it has a bead in it or not. When working the stitches with beads, it might be a little bit of a tight squeeze to get your hook in there, but you can do it.
Work a slip stitch into the second chain from your hook, (View N) then work 4 more slip stitches for a total of 5. (View O.) Next, work a beaded slip stitch. (Views P & Q.) To do this, you're just going to slide a bead close to your work and then work the stitch as usual.)
From this point on, you're going to work 1 beaded slip stitch, then 3 ordinary slip stitches, all the way across the row.
Again, your beads are falling to the back of the work, so when you look at it from the side you are working, you can't see what's going on with them. (View R.) It might help you to turn the work over and look at it every so often to make sure everything looks OK with the beads. (View S.)
