Bumpy Circular Dishcloth

I now have a video tutorial:

So now I will post pattern for this circular bumpy dishcloth.
I had found it is best to do this in continuous rounds. Joining rounds does not form the final bump in the row very well. I also used a 4.5 mm hook for these dishcloth, which is between a size G and H. Either hook size would work out o.k. for this dishcloth. Also the bumps are going to form on the opposite you are working on.

The pattern:

Ch 2, 8 sc in second chain from hook
Row 1: sc and tr in each sc
Row 2: *sc in next stitch, 2 sc in next stitch* repeat 7 more times
Row 3: * sc in next stitch, tr in next stitch, sc and tr in next stitch* repeat 7 more times
Row 4: * sc in the next 3 stitches, 2 sc in the next stitch* repeat 7 more times
Row 5: *[sc in next stitch, tr in the next stitch] twice, sc and tr in the next stitch* repeat 7 more times
Row 6: *sc in the next 5 stitches, 2 sc in the next stitch* repeat 7 more times
Row 7: *[sc in next stitch, tr in the next stitch] three times, sc and tr in the next stitch* repeat 7 more times
Row 8:  *sc in the next 7 stitches, 2 sc in the next stitch* repeat 7 more times
Row 9: *[sc in next stitch, tr in the next stitch] four times, sc and tr in the next stitch* repeat 7 more times
Row 10: *sc in the next 9 stitches, 2 sc in the next stitch* repeat 7 more times. Finish off.
