When I spoke of gluing it in sections I was referring to not trying to put glue on the entire quilt at once, but do it by sections (I said do it by quarters, but doing it by halves might be a better option for you). It is not a problem... I'm not very clever and I've done it (thin lines of glue onto the batting and then start at the center and smooth the fabric down onto the batting, do the other half the same way. If you blob too much glue in a spot, relax, it will all wash out later.
Hope you find a way that is good for YOU!
