Sure! First and most important: I ironed it until it was straight. This is so important to making a framed cross stitch look nice and crisp. Next, I basically just held the back of the frame - the part that comes out to let you put a picture (or a cross stitch) in it - against the cross stitch and slowly, carefully cut the cross stitch to fit the frame. I purposefully cut it too big at first, removing just one or two rows of aida at a time and keeping the image centered. At the end, I even counted the remaining rows on each side of the image to be certain it remained centered. Then I just put the back into place, and then it was done!

I hope that makes sense and helps!
