I bought the roller bottle when BonnieJP first posted about it. I love it. It's the only way I baste now. I buy Elmer's School glue by the gallon at Walmart. I glue every inch of the quilt so when the glue dries the quilt may look puckery but that is because the glue shrinks when drying. I press the quilt and it's flat and smooth and stays that way until I get ready to quilt it. No need to glue as much as I do but my quilt sandwich is flat as paper and doesn't shift at all. I have used the basting spray recipe in the link above and it works fine. I find a glue stick is messy for large surface basting.
