I added fonts for letters A, D, T, and K.

All of my letters work perfectly fine n their own.
However, when I check with commit, some of my
grids are rotated and I am not sure why. but I
submit my work anyway. It did frustrate me
that my end-work didn't look how it was supposed
to, but individually they look perfectly fine.
I spent a good amount of time catching up on this
course work so I think being in the same productive
flow for a while helped me get this assignment
done. I did have to re-do the curves multiple
times, but I knew what I wanted my end-product
to look like so I did my best.
