Welcome to the board!
I'd get a jelly roll (like Moda Lollipop) so you have a lot of variety, and then I'd make one of these:

Fast and simple, lots of visual interest and can be used for many years.
If you use the search function at the top of the topic page, you can search fabric sites and find most of the go-to sites most people here use.
Good luck, can't wait to see what you create.
IMHO
