Cool T-Shirt Designs for "Horse Riding Grandma"

White design that is going to be applied on a Black t-shirt.
You may use maximum 2 colors (gray for shading and white), but we prefer 1 color (white) only.

1. Use the following phrase to make the design.
- "I'm a Horse Riding Grandma. Just like a normal grandma except
much cooler."
2. Design should be able to be easily replicated.
- For example, the design should be easily changed to "Grandpa" from
"Grandma". "Horse Riding" could be easily changed to something else
such as "Fishing".
3. Deliver in PSD with all Layers (including Text Layers).
4. Size should be at least 1000 x 1000 pixel.
5. No more than 2 colors.
- Gray for shading and White
- But we prefer 1 Color (white) only.
6. Using 1 color only (white) will increase the chance of winning the contest. (unless the design is so much cooler looking with 2 colors.)
7. Should be unique from the original design we provide (attached file).
The more unique and cool looking, the better.
