Hat sizes are approximate. Your gauge does not have to be perfect. The hospitals will find babies to fit all size hats. Fabric paint is a suitable alternative to embroidery on finger puppets. Please keep pairs of bootees together with a safety pin.
Bootees stay on best if there's a ribbon or chained yarn tie around the ankle.
Pom pom makers are available at your local craft store or make one as follows. Cut the loops and trim the pom-pom until circular. Tie onto top of hat. To attach a satin ribbon bow to the top of a hat, thread ribbon onto a tapestry needle. Weave in and out of the top of the hat.
