DWR part IV - need help

This is not the finished quilt , it's just the left row that is assembled, the rest are pieced pieces LOL pinned to my very rudimentary design wall. After putting it up there I realized that I had used the wrong melon wedges for the right side of the circles, so there I was again working with my trusted friend Mr Ripper;-)

After finishing that first row, I realized yet one more thing - the half bits of the inner pieces (of-white ones) I had cut to fit into the place where the red arrows are, don't fit when the blocks are turned this way (according to the description I had) and not the way I had pinned them at first. No matter how I turn these bits or the inner pieces, the simply don't fit.

The thing is - I do not want a scalloped edge but a blue border from Kaufman Fusions, because I think it' a nicer finishing touch than scallops. Oh don't get me wrong, I do love scallops in their right places, but IMHO they don't fit in with this scheme.

So dear sweet readers - do you have any idea on what shape of white  I can use to make the edges even?? I thought about getting some white paper underneath and outline, but somewhere in the back of me head a nagging voice say "you can bet your sweet patootie that your edges aren't even. Hmmmmm I might have to outline each and everyone of these???? Thank heave my MIL isn't moving until in 3 weeks:-D
