What type of wood to use

Pretty new to the X-Carve world, and woodworking in general. I’ve made few things using 1/2 MDF primarily for name cutouts but it seems anything with different depths doesnt quite get the quality I’m looking for with MDF. What do you all use for logos and other designs?

I use hard maple for my layered signs, I also use PVC board a lot. Look up Steve’s projects 100’s of pictures for examples
