re: Marquetry by my 10 yr old granddaughter

Tim used poplar which dyes well and if you keep to the same wood (thickness) you can sand (or not) since it'll all be level already and you can keep painted or dyed pieces brightly colored like the beauts Tim shows.

For veneer sources, you can get packs of good sizes for marquetry from the big mail-order woodworking outfits or find others.

I have bought a few marquetry packs from veneeringSupplies that were excellent for variety (50 sq-ft).
