I took a punt on a couple of auction lots and bid on the internet for them.
How about this.....
sycamore 13 1/2 x 2 1/2
oak 12 x 1
12 x 2
13 x 1
14 x 1
elm 13 x 2 1/2 (spalted burr)
13 1/2 x 2
beech 11 x 2 1/2 (spalted)
13 x 3 (spalted)
ash 8 x 2
9 x 2
mahogany 6 x 1
6 x 1
12 x 1
...all 14 pieces for £25. I smell a profit!
...and that was just the first lot....the second lot had a big block of camphorwood, a 2x2 of zebrano, a small lump of Australian burr, an elm burr and a load of banksia nuts.
