help decyphering a pattern

Hi all,
I would like to reproduce the pattern of this cushion (the one on the right in the picture). I am having troubles understanding the number of stitches to cast and how many stitches per braid.
Any help is appreciated!

It depends on the weight yarn you’re using and the size cushion you want to make. That’s quite a detailed design on the cushion so it may also depend on how much detail you are going to incorporate into the knitting.
Once you’ve knit a gauge swatch, you’ll know.how many stitches/cm and you can then figure out how many sts to cast on.
