I finished my 25-patch top and I'm loving it! It got kind of large--- almost king size! I had to put it on my driveway in order to get the picture.
The strips were cut at 2-1/2" and the blocks finish at 10". My sashing was cut at 2-1/2" also. The pattern is by Pat Riley of Life's A Stitch in Janesville, Wisconsin. The striped sashing fabric came from her shop too!!
