What is amazing about this is- the effect you created looks like the pixels in a photograph- if I'm seeing the pic right;)))- and I think I am :)- it's one of those "happy accidents"- I get lots of accidents- but none so "happy"- very clever! And you are right-mom loves it and that is the key. I've been reminding myself recently to stop announcing all the mistakes I made in a piece when I give it to people- just let them love it; mistakes I know about and all!
Now, see, I thought this was amazingly artistic with the way the colors seem to shimmer. I figured you must have a great eye for color placement to achieve that effect! No oops that I can see!
I take it back, there is no mistake in this quilt ;)
I second the pixellation effect. I think it's a serendipitous 'oops' where you've succeeded in creating something entirely different from what you intended but the new thing is great in it's own way.
It looks absolutely amazing! I love the pixel look!
