Struggling with a bernat pattern

[acv1987]

Hi There - I have been attempting this "RIDGED CROCHET BABY BLANKET" pattern from bernat (https://www.yarnspirations.com/on/demandware.static/-/Sites-master-catalog-spinrite/default/dw648bb050/PDF/BRC0202-013778M.pdf) with the suggested yarn (dappled misty jungle green) for over a year now. I have done it 3 times and still can't get it quite right. It calls for a L hook which is entirely too small for this weave. I've now tried it with a N hook and it is still too tight. Thinking of trying it with a larger hook but am very discouraged since I've done this so many times and also the yarn is now out of stock and I think i would need at least one additional skien to complete in a square shape. Has anyone attempted this pattern or have suggestions?

You said you can't get it "quite right"----In what way is it wrong?  

There's a lot going on in the pattern, with all the post sts and keeping the incs and decs lined up right, I can imagine I'd have difficulty keeping it all on track.

couple of them note it turns out very small, if that helps

Ugh, the whole thing is post stitches, so is going to be a massive yarn eater because a good portion of each DC overlaps another stitch.  Otherwise, it's 'just' a typical ripple pattern, which is theoretically simple but in practice a bit of a pain because you have to count your stitches religiously.  I KNOW this and have still messed up the ripples I've made at some point when my mind wandered and I've stopped counting.   rip, rip!

All I can recommend is, if you are afraid of running out of yarn, is to make it in plain DC instead of the post stitches--without the overlap, it will get taller with fewer rows.  And yes stitch markers, and count count count.
