I picked up something here that i read that was one of those "Ah~ha moments"
I have a habit of not pinning my borders to the main quilt - afterall, I'm just sewing a straight line!!
But, when i put this last piece on, I'll be making sure that my 2 side pieces are the same length and i'll be pinning the 2 pieces together. Hopefully, the one side won't "grow" when i sew it...
