I do not understand the pattern

My pattern says
“Work in stocking st, dec 1 st each end of needle as before every 4th row from previous dec 8 times more”

This confuses me, can somebody explain what i have to do??

Welcome to KH!
Make the decrease on the 4th row from the previous dec, then dec at each end on rows 8,12,16,20,24,28 and 32.

Thanks for replying but…

Maybe i am just too stupid but, i think this part is creating the waist. And if you do it evere 4th row isnt happining on the same side of the work everytime?

You’re decreasing at each end of the piece so the waist shaping will be at both edges. Is that what you mean?
It’s not stupid, believe me. There just aren’t any stupid questions here!
