Well one night while I was upstairs getting the boys to bed, Amelia was downstairs with Hans at work drawing and writing. Apparently she asked Hans for the glue and because Hans was busy at the computer, he handed her a bottle of glue, no questions asked.
As you can see on the picture Amelia wanted the paper to really stick to the wall, logically she covered a quarter of the paper with glue. By the time I came down stairs, the glue was on its way to drying and those papers are still plastered there to this day.
