I've done that once. Maybe this will give you an impression whether you like that look or not:

Generally agreed. I think you can have metallic thread/wire woven into cloth, though, so there's definitely a case to be made for using actual metallics.
But yeah, generally this is where you want to go with traditional 2D painting techniques since it doesn't get much more 2D than stitched art on cloth.
