I just made one --used up a bunch of old jeans. I was going to make it twin size but decided due to the weight it would be more of a stadium throw. It is big enough to sit on and pull over the legs, or fold and lay out on bleachers. I've got a 2nd one ready to put the batting and fabric in then need to stitch down the "petals". I will make a 3rd one but will actually follow the instructions to make it! I figure this is the one everyone will remember--not the appliqued or pieced.
Your's looks great. You did a nice job. Whoever gets it will certainly love it.
