batting packages tell you how closely/densely the quilt HAS TO BE QUILTED in order for the batting to remain flat and the way it is supposed to. some batts need to be quilted very heavily *(like every 2-4") others can be quilted further apart (like every 10") if the batting is acceptable for tyeing your quilt the package will say (WORKS FOR TYED QUILTING) or something to that effect.
if you do not want to quilt or tye your quilt you should use something else for batting...like a blanket, fleece, flannel...something that will not pull apart when it is pulled on or wet.
it is very important to actually read the packaging for your battings. there is a wealth of information on the package.
