The colors work well together in the star.
If it was laying "flat" before you washed it, you might be able to block it back into shape.
Start by getting the axis lined up properly, and then you can pat/nudge the star points into better alignment.
It appears that the pieces may have gotten stretched at the V's of the stars a bit while handling and that's why you have that overlap. Try to block those V's into 90 degree angles - some of those angles look like they might be a bit larger than that now.
I think that also using correct sized setting squares and setting triangles will take care of some the problem.
