Here's 1 I made for my daughter from her sorority tees in 2007. I used fusible batting that looked like felt on all pieces, sashing, cornertsones & all. Then I sewed it together in sections, leaving an inch or two extra backing around each square. It's better to leave extra that you can trim away than end up with too little. I put the blocks face to face and sewed a seam that would be like an open seam on the back, then triimmed off one side of the extra backing. I folded the other side (about 1 inch) over and turned under the raw edge & hand stitched it down. The extra backing made the binding, as well...just fold over and hand sew it down. I did not quilt it. I did top stitch on the sashing as I finished each block...before putting it together.
