Color Wheel Quilt - It Has Finally Begun!

This is a project I've wanted to do for YEARS. I've always loved all those gorgeous color wheel quilts out there! I've been planning this in my head for soo long and I knew I wanted to do something unexpected and new. There's a lot of stunning ones out there and I didn't want to risk replicating a design already out there. So I ended up going with something a bit more unusual (I hope! I haven't seen anything similar at least ^^). The reason I chose this version of the color wheel was because I not only intend to use it for decoration but for actual color picker help in my sewing area. So here's the beginning, the center of my color wheel quilt.

I used this tutorial from Sew Mama Sew to make my pattern. As you can see I used my Tonga Treats, Strip Treat - Hard Candy strips for this so I had to sew them together to fill the space I need them to fill. Now I'm terrified that I've missed some step in this whole piecing curves thing that will make my center or outer ring unusable... But we'll just have to wait and see =)

I'm still waiting for my white fabric to arrive so this is actually at a bit of a standstill right now, which might be good as I'm currently considering what I want to do in terms of border for it. If I had the background fabric here now, knowing myself I'd probably already be quilting it! Any suggestions are most welcome.

I've picked out all the colors I want for the actual wheel part of the quilt too, that was sooo much fun!

The only ones I'm not perfectly happy with are the greens, but they will do =)
