But the pattern seems clear. The only nuance that I didn't know how to reflect in the pattern: the first 4 yarn overs in the rows are regular, yarn over and yarn over... but starting from the 5th and throughout the height of the repeat, I made a twisted yarn over, so it wouldn't create a hole, but just an additional stitch.
Please note that all even rows - wrong side rows - are knitted with purl stitches. Individual stitches are drawn out - follow them according to the pattern. The empty squares are purl stitches.
