What trade did Shakespeare's father ply as noted in the biography, Will in the World?

Shakespeare's father was a designer and maker of gloves, which in Elizabethan times could be functional or extraordinarily decorative. John Shakespeare specialized in the latter sort, gloves made of expensive, well tanned leathers and expansively decorated. Will Shakespeare presumably worked in his father's shop and apprenticed in the trade - references to tanning, various leathers, and to the layers of protection and masking offered by gloves abound in his writing.
