Are you using straight of grain binding or bias? I don't use bias binding anymore unless I have a scallop edge. If you were using straight of grain binding and you still have the border puckers, you'll need to find out why. Do the borders have too much fabric...Am I stretching the binding too much? I usually run a row of stitching along the quilt raw edge before putting on my binding. This row of stitches let you know if everything is where it's supposed to be and you can make adjustments if necessary before binding. Tommorrow is bound to be better...right?
