I remember having to make a "how to make ....." speech in public speaking class during college. I did mine on how to make book covers and envelopes with left-over wallpaper.
Do you know, those little pieces of soap that are left from a bar of soap and are too small to use anymore? So I Put a bunch of those little pieces in a saucer and into the microwave and they all melted into one bar of soap.... ...and to think i used to throw all of those little pieces away...haha
