individual or carve a pattern or a personal design, as for the finish you could use straight sawn timber
and simply sand it, without any other detail being introduced.
This one is from an Oak offcut.
Step 1: Tools and materials:
Fret saw, Jig saw, Scroll saw or band saw.
40mm Forstner bit. (but a spade bit would do - an auger would make a real mess).
2mm twist drill. (or nail).
Sharp 1/4" chisel. (or knife).
Oil, wax or whichever you prefer. - I go for natural wax or Danish or Tung oil.
Suitable wood, approx, 12mm - 25mm thick, 250mm - 300mm long, 50mm - 75mm wide - These measurements are only a guide as you can use your own design,
