Fat Quarter Quilt- Part 1

I have started a really BIG project at least for me. I am attempting to make a quilt for Harper's new queen size bed. We bought a new bed about a month ago, so Harper got our old bed. I have been looking around at various places and just couldn't find anything that I really loved. Inspired by Carrie's quilts I decided to make a larger version for Harper's bed. I wanted something simple, modern, and colorful. I also wanted to use precut fabric, so I sketched out a plan using fat quarters. (Sorry in advance for the horrible photos.)

After looking at tons of fabric options, I settled on Kumari Garden.

I pre-washed the fabric. Then decided on a pattern. As you can tell the kids were very helpful during this process.

I pieced the fat quarters together in rows.

Then I made my quilt sandwich. I am using a queen sheet for the back and warm and natural for the batting.

I basted the quilt together with pins.

Now I just need to decide how I am going to quilt the thing. Any suggestions?
