Here's what I have done so far on Grand Illusion.
You can't really tell from this picture, but the rows across are all that is sewn. This is a wild quilt. When I make a Bonnie Hunter mystery, I like to use up odd ball scraps. This time I had to buy some orange. The rest of the quilt is from my stash.
In my mind, a mystery quilt is a crap shoot. You don't know what you'll get, and you will like some mystery quilts more than others. It bothered me to hear unkind criticism of this pattern. This pattern was a free gift. How should you react when you open a gift? You say 'Thank you!' You don't say 'This really isn't my taste. I'd like another style or color'. And if you are compelled to say something like that, you don't post it online where the person who has created the pattern and given it to you for free is likely to see it.
There are kind ways to critique, and there are unkind ways. One of my child's teachers used to teach, 'three pats and a wish'. The kids needed to say 3 things they liked before they said the one thing they wished was different. I think we need to be gentle, especially when we critique something someone has made.
