Oh, I love it. A little confused how you used the 5" and put it together. I love charm packs too.
Hey Toucan - one charm pack comes with 42- 5" so I would think two of them would be plenty for a lap quilt.
I know how to sew 9 patches together and then cut horizotaly and vertically across the center. Just have to picture doing it in a larger scale. Thank you for sharing.
