ghillie suits are great for alot of applications. I could see you using it for coyote, why not? Make sure you store it outside for a few days before you go hunting, to get the scent smelling natural and also that lets the elements at it for a bit, tends to weather it a bit, so it doesn't look all shiny and clean!
Military snipers suggest taking it out on a dirt road and dragging it around a bit to get it nice and dirty too! While ghillie suits seem a little excessive for hunting, they are fun to use, and amazingly effective vs any eyes whether human or animal. I've built two of them myself.
