feathered circle

[Mimis-quilts]

I am making this carpenters star quilt after seeing one one here that someone else was making, as you can see I have started quilting it...I've always admired the look of the feathered star quilting patterns, but until today never tried to quilt one. On the front side it looks pretty good, but on the back side (purple side) it looks pretty sloppy. Anyone have any good techniques on sewing this pattern. I know...practice makes a little more perfect...thought someone out there would have a "rhythm" to follow when actually sewing it.
Thanks for any suggestions.

In case you are wondering...yes this is for my oncology project...and I recycled a scrub shirt and one of my husbands shirts to make it.
