What lovely memories you brought back with this.
Messing about with coloured sweet wrappers was something I enjoyed as a small child too, used to like watching little silver cups (like trophy cups) being made from the silver foil from sweet wrappers, I could never get them quite as perfect as my dad did. Think Rolo wrappers were used, for the gold foil. One thing that always delighted us was when he wrapped up the last 2 rolos in gold foil and gave them to me and my sister "for later on". They were precious then, sweets. The other thing I remember is a Mars bar being cut carefully into slices ., like slicing bread, and shared out. I swear the mars bar tasted better sliced.
Try telling a child that nowadays, they think you're barmy!
