The easiest and fastest quilt top I ever made was a take off of the jelly roll race...I cut 3 inch strips from Christmas stash fabrics......random lengths....and sewed them end to end using a 45 degree seam....the more 3 inch strips that you sew together, the larger the quilt top....when you think you have done enough, sew some more....then bring the first strip that you started with and lay it right sides together with the last strip....stitch...boring, now you have a double strip.....bring the end up again and with right sides together, stitch together. Less boring this time because it is shorter...repeat the process until it is a proper looking size...a large quilt top can be made in less than a day...there are better directions from others, but this may give you inspiration...I'll look for a picture to post....
