I liked the look of dgom's trivets and the fact he mentioned using up scraps. I have plenty of those.
Slight changes, I went with 4 x 2 slats to get about 5-3/4" square (3/8" thick slats). I also used 1/4" dowels at the junctions just for the extra hold to deal with typical spousal abuse ðŸ¤
Made with red oak, fumed and soaked in Watco.
Radius on the edges...
... and silicone footsies
Great weekend project and I've enough scraps to make 10K more.
