Correction on adding a strip of 1/8th. It’s 1/8th plus half an inch but I still wouldn’t do it. I like Kass’s idea if your center seams aren’t wide enough to make up the difference.

As for adding a 1/4 inch border, you’d actually have to sew a 1/8 inch piece (plus seam allowance of 1/4 inch) all around each side to make it square. That would end up adding too much bulk in my opinion. I wouldn’t do it. Question: are you measuring with an acrylic ruler or are you using your mat markings? Don’t go by the mat as the lines are notoriously wrong on most mats. Measuring should be done with an acrylic ruler or square. And be sure to measure as you go to pick up small errors before they’re too large and you’re practically done.
Hope that helps.
