I don't glue anything down until I'm happy with everything. If I'm not happy with it or I just feel it's unfinished, I continue to work on it. Sometimes after a day (or several) I decide that I like it after all and don't do anything, sometimes it gets changed around completely. But it's all about whether I'm happy with it.
I actually don't like all those over-decorated pages that seem to be so popular right now. I like my pages clean and simple with a little decoration, not a lot.
