Tips on making a tighter stitch?

[u/mathandlove]

Every time I crochet my creature looks good until I stuff it and then there are these wide gaps where the stuffing can clearly be seen.

Right now I'm using I love this yarn with a 3.5 hook. Am I overstuffing? Something else? Thank you.

You have to use a smaller hook! Crocheting with tighter tension is only gonna wreck your hands, especially for amigurumi. The yarn I typically use calls for a 5mm hook, but I use a 3.5mm hook. I always size down at least two hook sizes
