   Forma — The Studio Sample Book
   A whacky-but-committed organising idea: workshops are material samples
   laid out on a warm studio bench. Cards are paper swatches pinned to the
   bench, tagged with a craft pigment, slightly askew. The detail view is a
   specimen lifted off the bench for closer inspection. Saved items are
   pinned to a personal board.
