HI Brenda! Love how your block came out - its very pretty. As for the difference in the pattern... not all screens display the same size. My own screen can be enlarged and reduced at will using my keyboard which affects screen prints.. You might try printing the pattern and checking the test square for accuracy. It should measure exactly one inch by one inch. If it doesn't you need to adjust the printer settings. Regardless, I wouldn't change a thing unless you're unhappy with it. Its your quilt!
