You're going to do a couple rows just on these bobble stitches. If you yo k 3times in the same stitch you have 6 sts. Turn and sl1, p5, then turn again to sl1, k5, then turn and p2tog 3 times which leaves you with 3 stitches. Then turn and do the sl k2tog psso on them which leaves you with 1 stitch again. If you take some leftover yarn and do a little sample and follow along step by step you'll understand how it's done a little better. Some things are hard to 'see' in our heads, but make more sense with stitches on the needle.
