well I am my own worst advisor. I read, reread and still did it wrong. I put the bottom of my ruler on 3.5 across the strata but at the bottom. *sigh* what was I thinking ??? lol at least I only cut one strata. I'm so hoping we don't use much more of the E/F fabric. Will have enough of the other five but this one is looking iffy. another big *sigh*. Now have to cut more strips, sew another strata and learn from my mistake. Put the RULER line on 3.5 inches, not the fabric.
