This pattern is quite versatile and adaptive. You might need to use a different size crochet hook depending on the yarn thickness, hand size or tension. I usually use a 3.5mm hook but have also used a 3.75mm and a 4mm. You can test the fit by making the beginning chain and seeing how it fits around your hand. You want it to be snug, but not too...

This is a pattern to crochet an eye motif. You can attach this motif to other garments, use it on its own or create multiple to make something like a wall hanging.
