Biased Carpet Bowls

Requires a carpet 6' wide and only 30' long, using 3 7/8" diameter bowls.
Each set consists of 4 pairs of Black and 4 pairs of Brown bowls with a White jack. Each pair of bowls is distinguished by coloured scores of Red, Blue, Green and White. The bowls, despite their smaller size, have been machined and finished to give as accurate a bias as the finest lawn bowls.
