By "dimensional" pattern, I'm not sure if you are meaning a traditional teddy bear? or a quilt where the bear has some 3-D embellishments?
This is one that I have made and want to remake with 3-D effects.
I can think of lots of possibilities .... bow around the neck or a neck tie; buttons; extra batting for head, tummy, feet, etc. to have them puff up more than the flatness of the rest of the quilt; different fabrics for textures, etc.
