These leather mushrooms are roughly 2"x 2" in size. They have a huge variety of colors and textures for the mushroom caps, sometimes with one-off pieces of leather. What you see in the picture is just a small example of the wide selection.
 
This is a random grab, but I will try to accomodate a color range. You can enter "earth tones", "Bright colors", etc.. You can also leave the entry blank for a truly random mushroom.
