Made from scrap cedar, firewood and it appears to me to be redwood heart.
Just laid-out on the board, drilled for blade insertion, then cut. No particular font, whatever the wood wanted when I started, is what it became.
The bases are firewood; species unknown, but very hard.
Lightly torched for grain enhancement, then a quick spray of polyurethane for a finish.
Dollar Tree foam letters used for a scratch free base.
These will be given to the grand-daughter.s friends that often play in the playground next door!
