I am a total newbie to scroll sawing. I am about to start my first portrait but I am not sure about some details. I will use birch ply but what thickness? The pattern is about 12" x 16". Does it look bad to go too thin or too thick? Or is it just a matter of taste? Also, what are some options for backing it? I've thought about poster board (seems kinda fragile), painted ply, stained ply, and felt glued to ply. I just don't want it to end up looking cheap because of the backing.
Thanks in advance for any input.
