Several people emailed me wanting to know the number of units if they want to make their quilt a different size. If that is what you want to do I suggest you wait until the mystery is over and then figure out what you need to do to make it the size you want. I really don't have the time to plan this out in every size out there. ONE SIZE. If you want it bigger? You can make more blocks when you go to set it together. If you want it smaller? You'll have extra blocks? Or like I said...just wait until the mystery is revealed and you can plan it the way you want it.
If you want to use larger strips? I can't tell you how that will turn out either. I'm just going to post what I am doing for you to follow along with me. If you want to color outside the lines.....that is up to you!
If you have already ironed your rail fences towards the center strip..I made a mistake there. It happens. I am winging this as I sew myself, so my mistakes my sometimes be your mistakes too. I'll try to get a few steps ahead so this won't happen.
If you have pressed your seam allowances towards the center strip on your rail fences, simply take a few minutes and reverse the process by running your iron down the back side of your block unit and pressing those seam allowances AWAY from the center. This is important so the next units (which have more seams) will butt up correctly. It won't take you long. You can grumble at me if you want, but I want to be sewing without having to flip seams all out of the way:c)
