Cut your cardstock by making a circle about the size of the wreath. I traced a jar lid and it was perfect. Take your felt or fleece (or even flannel will work) and cut it into 2 1/2" squares.
Cut one of the squares in half and roll it up for the body. A spot of glue will hold it in place. Then glue on the cardstock to the bottom of the wreath. Just kinda look to see which side is flatter and use it. This is something that I decided to add. The ones I saw on Pinterest didn't use this but they used alot more excelsior and, its just me, but I thought it looked a little sloppy.
Press the card stock down firmly and turn it over and let it dry, wreath side up.
Lay the baby on the fleece as shown above, and wrap him burrito style in the fleece. Glue some moss or excelsior to the dried wreath and add in baby Jesus. (You will want to glue him down) Cut some wire for the hanger. I used about a 10" piece of black wire but you can make it longer if you want more little curls on it. I secured mine to the wreath and then curled it by wrapping it around a crochet hook. I glued it on and there you have it, your Away in a Manger ornament.
Again, make this your own. I had to glue a bit of the fleece to the top of the head because there was a hole in it. You could paint on a little bit of hair. You can use some straw to fill in the "manger". You could wrap the baby in homespun. Instead of black wire, you could use rusty wire. Instead of a star, you could glue on a heart, or put on a tag.
