I really don't like safety eyes. I think they are mis-named. They say "Not safe for children under 3." How is that safe?

Anyway, I make my own and stitch them on well. So, this is my version of safety eyes.

I've adapted several versions. I really wanted more of a "bigger eye" look. So the main eye is made with the eye color, and black and white just a bit for enhancements. I hope it works as well as I think it will.

The thing that makes it intermediate, is a french knot, but there is a video tutorial included.

I just found this pattern and thought it might be what you're looking for also. So, here's a link to that one. https://ribblr.com/pattern/simple-crochet-eyes-crochet
