It depends on your level of graphic design experience/skill, and how much you’re willing to spend. Overwhelming consensus is not do it yourself if you can avoid it. Creating a truly effective cover that attracts readers is a science. A cover that an author thinks is cool may not be the most effective at driving sales, pre-order or otherwise. You will get a pro cover design from Inkshares if you get funded. But it can only help your campaign to have an effective cover upfront. 

I don’t know if I’d call mine cool, but I have made my own covers, even if just something temporary. Definitely seems to help.

I see all these cool book covers and wonder if each writer designed their own, paid someone to create the book cover, or if Inkshares provided the book cover when writers hit a certain level of followers. I just took a Google image that seemed to fit well with my story (one that allowed reuse with modifications). How can I get a cool cover?

I like this statement. It makes me think of a drop of water which then leads me to think of water’s fluidity and how that translates to time.

I loved this description of the neighborhood homes.
