Since a few people have asked for help in creating a queen size Penny Quilt, I put together a mockup of what the layout would look like.
This is not a pattern that I will likely be adding sizing to for logistical reasons, but it is easy enough to add more blocks to make the quilt larger. You will need to make your long sashing strips quite a bit longer as well.
This mockup is done in Sincerely Yours by Sherri and Chelsi. The finished size of the quilt would be 92" x 110" which is a perfect size for a queen bed. I hope this is helpful if you are going big with your Penny Quilt!
