Second guessing a mystery

Do you ever second guess the work you do on a quilt - to the point where you are willing to take a few steps backwards and rip out the work completed thus far to fix it?

I suspect if you've worked on several quilt projects, you have encountered this challenge.

I'm starting on the final step of assembling the Bonnie Hunter mystery quilt pattern - "Grassy Creek".  The challenge with a mystery is even if you follow the directions given, you may want to change some things when you see them finally coming together.  In my case, I have a sort-of scrappy quilt.  I'm using multiple fabrics for each colour selection, but not a truly scrappy quilt.

Case in point - here is the assembled first block:

The dark teal-green fabrics are in the same colour family, and I wasn't really happy with the result.  I took a second block, used more of the teal-green fabric and laid it down on those four corners and took another picture:

Suddenly, the star popped for me, and as much as I didn't want to rip two assembled blocks apart, I knew it was better now than never.

I think that would be two pieces of advice that I have received that I would share with you:

1.  Assemble a corner of your quilt top when doing a mystery, or hang your blocks on a design wall, so you can see if anything is going to distract you and eventually bother you.  If you squint your eyes and can't see it - leave it.  If you squint your eyes and it still bothers you, fix it now.

2.  Never underestimate the power of a photo to give you some perspective.
