Type of Wood able to be Curved around Line Bent Acrylic
If you want something that's flexible, then you need the thinnest board you can find. Something like this might work since it's only 1/4" thick. If you need a thicker surface, then glue two or more pieces together in the bent position. I've also seen boards placed in a hot steam to make them more flexible. Get plenty of extra wood to be prepared for some trial and error.
