how difficult would it be out of 10 to cut these? I know on this floor there are an awful lot, but to do enough to cover a box lid wouldnt need that many i wouldnt think, all be them a bit smaller. The advantage is that there are no internal cuts, so a cheap scroll saw would not be penalised like it otherwise might.
I think it looks fantastic, particularly if using a few different timbers. Stack cutting veneer would, i guess, be another option.
