Converting pattern from worsted to bulky yarn

[Eibell]

Trying to convert a pattern for a HHDC herringbone stitch baby blanket. Pattern calls for 4 worsted- with I hook. cast on 105 stitches. 
I used #5 bulky and an L hook. Cast on 95 in. My stitches are obviously too close together as my first 6 rows are creating a semicircle instead of a flat row. 
I still have the correct stitch count, so how do I adjust the pattern for the heavier yarn?

In many cases you can use the same pattern by matching hook size to different weights of yarn and then compensating for your personal tension by going up or down a hook size or two. Normally in this case I would suggest using a larger hook but isnt an L the largest they make ---I cant remember.  Try crocheting real loose instead of pulling those stitches in so tight.

I have a M & N not sure if that is the ultimate solution but there are larger hooks available if you think that works.  I've only used them a handful of times as I rarely work in bulky yarns.

Its easy to make your foundation chain too tight which makes your stitches too close on the first row so using a larger hook to make the chains then switching to a smaller hook can help there.

Bgs - Hooks go way bigger than L, I own an S, about the size of a quarter (coin) in diameter.  19 mm, about 3/4ths of an inch.  (Looks it up) Holey Moley, they go all the way to 70mm, which is too big to give a letter to apparently!  That's 2.76" in diameter, (goes to kitchen) that's bigger than my rolling pin!

An L hook will still work with a US #4 weight yarn, and may be too small for a bulky weight.  Here is a chart that covers US yarn weights, and the hooks that work best with them.  https://www.craftyarncouncil.com/standards/yarn-weight-system

Note that they are bulky, super bulky, and jumbo (that last one is a new one to me, but I mostly use doily thread, so...)

If it is truly bulky, that works 'best' with  5.5-8mm hook sizes, which per another link on that site, https://www.craftyarncouncil.com/standards/hooks-and-needles would be a US I hook (the letter I) thru L.  So, it may not be your hook.  Is it an inline hook, or a tapered one?  If tapered, are you  forming the stitches near the tip (bad idea) or at the wide part of the shaft (the only way to 'use' the hook size to make the right size stitch).  I'm asking because as a new crocheter before the internet, I started out stitching the 'bad idea' way and my stitches were super tight, until I figured out I needed to shove the stitch to the wide part for the stitches to come out the right size and tension.

If you are making a foundation chain using the back bump, start over.  It pulls the chain tight.  Instead, with the chain facing you, insert your hook into the topmost loop.  This keeps the chain tension neutral.  I have never found a reason where that method is an improvement to the project; some think it looks better but that it not enough to overcome its drawbacks IMO.

Yikes thats a large hook.  Dh wouldnt turn his back on me if I pulled out one that big.  I very much dislike working with bulky yarn and large hooks. No lets be real I HATE it.   I have a N hook.  Did not enjoy the project so upon completion the hook was filed away.  I only dig it out to try to use up that awful eyelash or fuzzy yarn which I also dislike.

I am right there with you, I gave all my bulky yarn and large hooks away.

Yeah, I'm not a bulky yarn fan either, heck look at me I use mostly doily thread.  Eyelash is OK paired with worsted weight (I made a neckwarmer thingy years ago for an Alaska cruise ) but I wouldn't use it by itself...well I take it back, I wouldn't crochet with it by itself, but I made a couple of 'scarflaces', not crocheted but just the yarn cut to a length, tied at the ends and the ends captured in findings made for that purpose...maybe around 1990?  Along the lines of this, except the hardware not quite as fancy.
