The other thing I notice with this fabric is you mentioned cutting 3"x 10 1/2" pieces. It looks like if you want each piece of stripes to line up with the others, you will need to skip some fabric between strips. (the lines are not printed 3" apart) Will that cause a problem?
I mention this because recently I made a kit where the illustration of the finished quilt was doctored to make the print come out nicely when in reality, there was no way to make it look like the picture.
