A Lovely Year of Finishes: June Goal

My June Lovely Year of Finishes goal: machine quilt this polka dot log cabin quilt. 

I could probably fill out the year's goals with quilt tops that need to be machine quilted, but then I'd burn out! We'll start with this one and see how it goes. 

I have a couple ideas as to how i want to quilt it: possibly one large spiral design, possibly diagonal straight lines (though I'd like to branch out from straight lines!). 

Since there's, ahem, so much going on in the fabric of this quilt, I don't have to worry about the quilting standing out like it might on a quilt made from solids! 

If you have a suggestion on how I should quilt it, let me know!
