Oh, my! It's wonderful to see. But disappointing when you don't add the 1/4 inch to each section, too. I'm thinking you could change the print size for your printer and that may help or not. If it was a pp pattern it's going to make a huge difference in size.
Did you cut all the strips already? You can salvage it, make it to the size by making more blocks like you began with. It's going to make a beautiful quilt.
Hugs with understanding,
