(Additionally on Warm & White you can space your stitching up to 10" apart and the batt will not migrate.) And yes, if you do not want the aged look, by all means, do wash it prior to putting it in your quilt. Or might I suggest, use another type of batting. The higher the cotton content...the more the shrinkage...(the general rule.) Harriet Hargrave wrote an excellent book on battings, you might want to see if they have it at your library or guild library. There is really a ton to learn about batting for the hand and electric quilter. For myself, if I wanted extremely low loft and easy hand quilting/needling...I would use flannel, (washed in hot and dried on hot)...the finished product is pretty predictable and mades a wonderful looking quilt.
Just my 2 cents worth...
