Before you can build the inner structure for the posable hands and attach the rods, two patterns must be created – the Foam Hand Pattern and the Palm Support Pattern. Both patterns should be based on the original shape of the fabric hand pattern (without a seam allowance).

First, draw a few guides on which to base the two patterns. Start by tracing the original fabric hand pattern, stopping at the wrist line determined previously. Next, sketch a centerline down each finger and the thumb as well as a line to determine the base of the puppet’s palm.
The Foam Hand Pattern
Create the Foam Hand Pattern by drawing a line on the inside of the original hand shape, leaving a 1/8 inch space from the edge, except at the base of the palm.
The Palm Support Pattern
Draw the Palm Support Pattern within the confines of the Foam Hand Pattern. Leave a 1/4 inch space from any applicable edges of the Foam Hand Pattern, again with the exception of the base of the puppet’s palm. With small circles, mark the points where the florist wire (which will enable the posing of the fingers and thumb) will eventually be attached to the Palm Support Piece. Draw the circles in line with the centerline of each finger and the thumb and about 1/8 of an inch from the Palm Support Pattern’s edge.
Take a look at the figure above to see the relationship between the original hand pattern, the Foam Hand Pattern and the Palm Support Pattern. Click on the picture for a full-size printable version - wink, wink.
