I've not made a bargello, but your avatar caught my eye. I just made my first stab (:0) at English Paper Piecing. I know my cats love to "arrange" my quilt pieces for me, but this is the first time my cat was caught (true!) pulling the pins out with his claws and tossing the paper-backed hexagons up in the air & batting then like butterflies. It was too funny to get aggravated - until the third time. : )
