Here's the manger for Baby Jesus.
To get the instructions for making the entire manger, click here.

Cut a cardboard tube to a length slightly longer than your Baby Jesus. Next, cut it in half lengthwise. Trim an inch off the end of one half for the base.

Trim the base so it's narrower than the cradle. Staple together the pieces as shown, then bend down the cradle sides. Fill the bottom of the cradle (and later, the stable) with moss.
