I'm relatively new to quilting and amazed at how the quilts that make it to a show all lay perfectly flat- there are no waves in the fabric at all! I have basted a quilt with 505 spray, very carefully I might add, and it has slight waves on top before I have even done any quilting at all!
I love the way the no waves/no puckers/tight quilt tops show off the actual quilt stitches so well. While I don't yet aspire to this level of quilting, I ..like to improve my quilts by "heading in the right direction".
I have starched the quilt top before even spray basting, and ironed again right after basting to set the adhesive spray. I also add pins to the basted top. And, of course, stretched and ironed the top after quilting was finished. I realize that heavily quilted quilts will show fewer waves, but I have seen many pictures of quilts that are not heavily quilted that seem to have no waves, either.
Any tips on removing/eliminating "waves" would be greatly appreciated!
