I am actually happy with the leather options available.
1) Lined Cordura Nylon (Multiple Colors), 2) Silicone (multiple colors) 3) Wood Grain (Multiple options), 4) Chinoiserie, 5) Mount Fuji (Embossed, or picture/painting), 6)Paisley, 7) Tweed, 8) Corduroy Fabric (Multiple color options), 9) Denim, 10) Hexagon Geomentric Pattern, 11) Soft Suede Leather (or Pleather), 12) Rainbow, 13) Sunrise, 14) Embossed Image (Spider, Whale, PIne Tree, etc)..........
....99999) Red Plaid, 100000) Brown Plaid).
And I'm sure many people would select something different from this list, and from your preferred "Red Plaid". Brown and Black Leather would likely be to top of any survey.
