Crocheting instead of knitting?

Recently, I’ve been making a few little knitted dolls here and there, and right now I’m working on a knitted stuffed animal, and of course it strikes me again that while knitted animals are much softer, they’re also much harder to stuff. The stitches are much looser than single crochet stitches, so stuffing tends to show through easily; you really have to make sure to knit really tightly, and even then, it’s much more stretchy than crocheted items.
Now I’m wondering: if I have a pattern for a knitted amigurumi, couldn’t I just crochet it instead—that is, follow the pattern exactly, since every knitted stitch is essentially a crocheted one? Has anyone ever tried this? Would the proportions still be right?

Since I can’t crochet anymore, I’ve repurposed a few crocheted items and knitted them instead. So if it works going from crochet to knitting, it has to work the other way around too.

Best regards, Inge

You can’t just copy it one-to-one, because crochet stitches (single crochet) are about as wide as they are tall, while knitted stitches (stockinette stitch) are slightly wider than they are tall. So the crocheted amigurumi would end up “longer” than the knitted one.
I’ve done something like this before, but you have to do a lot of converting and trial and error. 

Dear Veronika, if your knitted animals turn out too loose, you could also try knitting with thinner needles. But crocheted items do actually turn out sturdier because the crochet stitches are thicker than knitted stitches. That’s why you also need more yarn for crocheted items. 
 

Yeah, Ruth, that’s what I was afraid of. Didn’t that make a difference in your projects, Inge?
Thanks for the tip, Petra—I hadn’t even thought of that yet.
Yeah, I do use the smallest needles possible, but at some point it just gets uncomfortable.

The “Su” got swallowed up in the Super Tip! Who did that? 🤣

It was a huge amount of math, and the pen and sheet of paper were used much more often than the needle, but it worked out in the end. I might still have that conversion somewhere, but where? ;-) When we moved down a floor, I threw a lot of stuff away.
Back then, it was a frog I’d adapted—one of my grandchildren loved frogs as a child :-)

Best wishes, Inge
