I’ve made these little fabric busting birds before for a different kind of baby mobile. For a friend’s new baby, I made a mobile with embroidery hoops this time. I wanted the birds to be movable, and perhaps taken off later on when baby is older and used as toys. To do this, I sewed ribbon to the bottom of the birds where their feet might be. The ribbon is slipped between the inner and outer hoops, then the hoop is tightened. The ribbon is long enough to be pulled from the bottom side of the hoop for better positioning and adjustments after the hoop is tightened. You can pull the bird snug onto the hoop this way.
