Very pretty fabrics and the black makes them pop! Your backing seams do not have to match up with any of the seams on the front. I much prefer a cotton batting, it's much easier to work with. If your machine has a serpentine stitch, a straight stitch than wiggles back and forth, you could just stitch it in curved lines down the length of your quilt and then turn the quilt and stitch from side to side. I had my 7 year old DGD do that on a doll quilt I helped her with and she thought that was fun. She could run the machine a little faster than when she was doing the 1/4th" seams! I had her use some thread colors that were in her quilt, which she enjoyed. If you have a walking foot, use it. The serpentine stitch is very forgiving and it takes away from the imperfections that might be in the quilt top. Good luck and keep quilting! :thumbup:
