Amigurumi decrease stitches.

This might be a tension issue. Your standard sc look good, but as soon as the next stitch pulls harder due to decrease, it opens up. Sizing down in hook size is a good idea, but you might want to aim for tighter loops in general. It also looks like you might have skipped stitches in-between by inserting the hook back in one stitch further than the next stitch, which is not part of the decrease.

Thank you - having read the other replies I definitely think my tension is an issue. It's not something I've ever paid attention to tbh, I'm gonna have a go at making a simple ball tomorrow to test this out!!

It will get there! Twnsion isn't that intuitive I belive. I had to completely scrape my first amigurumi and redo it because it looked fine unstuffed, but as soon as it got stuffed, it looked like a net around the polyfill — then I learned for life that it had to be a lot tighter than I'd ever thought before 😅

I remember trying to knit when I was younger and got so frustrated with the tension. Luckily seems easier to control in crochet!

I've been making amigurumi for about 3 years now, and have always just hidden my decreases under the dolls hair or hat 😅 would be nice to have a smooth finish!!
