It is fairly easy. You sew the top and bottom fabric wrong sides together, leaving an area of out 8 to 12 inches open. Then roll the quilt from one corner towards the opening and then reach into the opening and pull the rolled fabric thru the the opening and then put your hands inside the quilt and push the corners out and flatten the fabrics. Stitch up the opening. You quilt it after it is birthed. Most people tie the quilts.
My concern would be the Minky stretching before you have a chance to quilt it or as it is quilted.
