I wanted to be able to separate the eggs as I wanted, I was going to find some little plastic basket things with holes, but my friend suggested carpet canvas.  So I got plastic canvas, the 10 holes / inch sheets from Amazon then cut things to fit and zip tied it all together.  It will be reusable, I can clean and sanitize it.  I'm thinking the holes in the bottom will provide enough toe grips.  If not, I'll find a way to get thay drawer liner added.  I was trying to keep it good for air flow, grip, and cleanability.
