Thanks everyone! My top is now a flimsy with the inner border on. I don't buy much yardage (I have a HUGE stash of FQs-1 yd cuts), so I had to use a turquoise and "piece" in corners in a different fabric. I may have just enough purple to get a second 3 1/2" border bringing my top to about 95x95". That should be just fine! I'll post a final photo tomorrow.
