This is called "Abacus" by Vivienne Coles from London. She says "This quilt was made for the final part f my City and Guilds Part 2. The theme is Hong Kong Waterfront - Centre of Power/Finance - hence the name "Abacus". The fabrics are hand dyed using Procion/transfer dyes. I used applique and hand and machine quilting. I used techniques described by Linda Kemsball in her book entitled "Colour Moves" which I found inspirational."
