Hi Suz...I haven't but I would try if I had some! My new LQS hand dyes fabrics and they are $3.99 a fat quarter! I am now thinking I should try that with some of my muslin. I am not sure how to get that Batik look but think I will ask at the shop how she does that. I love all of the quilts and I have to say sewing with muslin is really nice. I have used it on the front as well as on the backs just never used the bleached...now I intend to do that! Years ago the choice our moms had for sheets were Percale or Muslin. Thanks Krystyna for this lesson in muslin...I have learned a lot on this board...it is such fun to keep learning!
