Up down pattern

This is a close up of my pillow (can be seen in Photos section), I cannot remember where I found the pattern, but it is very easy to remember so I even don't have a written pattern for this. But here it is to try:

chain -- (multiple of 6) + 1

row 1. dc all along, turn
row 2. 6 sc, * [sc into the below stitch of previous row, 5 sc], rep from *
row 3. (change color), dc all along, turn
row 4. 3 sc, *[sc into the below stich of previous row, 5 sc], rep from *
repeat row 1-4

I have never written a pattern before so I hope the above pattern is understandable :)
