I get inspired by what you write about this, I will actually take action on it and start collecting a "collage bag". Until now I have had a brown paper bag that I put "special things" in for those moments when you could sheer someone up with a playful gift or a beautiful notebook, but like you I too fancy a good hour's glueing and putting together - and doing the same thing together with my kids adds tenfold to that pleasure. Thanks for the tip!
