As much as I hate to say it I have done it.

When I went to use a new ruler, I was a little confused on the instructions how to make the block with their instructions compared to the pattern instructions so I made a sample first. After that the instructions seemed as clear as day to me but before that I was clueless.

Also when I print out a quilt pattern I made using EQ7 I make a sample block to be sure it's coming out exactly as I wanted it to.

I agree with JanRn!

You're definitely not alone, or stupid! I'm lucky to have a quilting buddy (my mom) who can help me fix pretty much any mistake; it would feel a lot worse when I do things like that if I didn't have her.

I did learn a long time ago to make test blocks, and (almost) always do now. I have a set of fabric that I always use for tests... it never occurred to me until reading this thread, but I guess those test blocks will make a pretty quilt some day.

I don't know if this will help you, but I'd love it if you would post the fabric and cut sizes, to see if anyone can come up with a new pattern (or fix to your plan) using what you have. It would be a shame to waste all the time and effort you've put in so far, and someone might come up with something really cool.

Thanks for all the support. I'm so glad that I am not alone when it comes to flying into the next project.

It turns out that it's not as bad as I thought. When I ironed the pieced block, it is just a smidge smaller than the larger piece. Maybe I can just slice a bit off.

Oh beleive me i have done the same thing!
