I consider mosaics pieced goods (even though ‘pieced goods’ technically really refer to cut and sewn things).My friends, husband and I jumped into the deep end of mosaics by taking a class on mosaic portraits. Katherine England teaches mosaic’ing amongst other things.
We were told most people learn to cut glass and glue or thin set it down before starting representational stuff much less people, but we skipped that step and went straight to making portraits.
We’ve since had Katherine teach us how to to make mosaic’ed balls too. Everything else mosaic’y has been easy-peasy compared to portraits.
