The best thing that happened today was the eureka-moment when I worked out that you can separate two pieces of paper that have been glued together using "power pritt" if you steam them over a kettle!
Power pritt (made by pritt stick, but comes in a silver tube and is much stronger than regular pritt stick) is my glue of choice for papercraft and zine making, as it is super strong so the pieces you have glued never fall apart. But this does mean that if you make a mistake, or want to change the positioning, you can't. As soon as you try to pull them apart, however gently, the paper tears and there are tears... But not anymore! Now I can just boil the kettle, hold the paper over the steam, very gently peel apart the two pieces of paper and start again.
