I forgot to mention, my favorite summer quilt has flannel in it for batting. It's best to use 90 wide to eliminate seams. If you want your quilt to look like an antique then don't pre wash the flannel. After the quilt is done, just wash and dry it 3 times and it is done shrinking. Instant antique LOL. If you don't want the antique look. Wash and dry the flannel before quilting. Do this at least 3 times and be sure to use the dryer so it gets all the shrinking out of it's system. If you don't want the wadded wrinkled mess when washing and drying then use the fan fold technique on the fabric before washing. Be sure to clip all 4 corners on an angle to prevent heavy raveling.
