strap for a shoulder bag

[starlight]

I'm making a felted shoulder bag. I'm at the point where I'm starting the straps. ( These straps are connected directly to the body of the bag).
I have 7 stitches on my double pointed needle.

The directions say: " K4, yarn forward, slip 3 purlwise. After you have knit a few inches, you will find you have 1 center garter stitch with a 3 st I-cord on either side."

I followed the directions. I knitted about 3 inches. It looks like a garbled mess. I did a booga bag with the 5 stitch I-cord, and it worked beautifully. When I slipped the last 3 stitches purlwise, my yarn is in the front of the needle. I wrap the yarn around back, slide the work to the other side of the dpn without turning, and k4, yf, slip 3 purlwise. It seems that the only stithes that I ever knit is the first 4, and the slipped purlwise gets wrapped around to the back. to where I start knitting those first 4 stitches again. Is this right, or What am I doing wrong? Any help will be greatly appreciated.

It's not like a standard icord where you slide the stitches to the other side of the needle. Knit the first three, slip the next, then turn the work. The yarn is supposed to strand across the back of those stitches when you knit the first three again. It helps to pull the stitches into a tube.
