I am making a wallhanging with a Japanese theme using 100% cottons. I have preshrunk all my fabrics. My question is about batting. Can anyone please let me know if I should preshink it or not? I have heard that washing a quilt whose batting has not been preshrunk will give it an antique look. I would love that, but is it appropriate with a Japanese theme? Is there such a thing as an "antique Japanese quilt"?. Any help or advice much appreciated.
