This uses Lion Brand Wool-Ease yarn and a size H hook. The finished size should be 4 inches high and 6 inches wide. This should be stitched with a tight gauge so that there are no holes that the bird’s legs might get stuck in.

You can start with magic ring, or I prefer to do what some people call a “sloppy slip knot.” I got this technique from Fresh Stitches, and it works well for making sure you don’t have a hole in the center when you crochet in the round.

Weave in all tails.

Here’s a look at the inside of the medium bowl and the other smaller nests I’ve made so far:

I used left over yarn, so that’s why some nests use different colored yarns. If you switch colors, just make sure to weave the ends in really well. I don’t usually knot, but I did with the tails on these and then wove in the ends since I wanted to make sure they were extra secure.
