How Did One Sheet of Paper Become a Long Classroom Garland?

A rectangular sheet of coloured paper was folded repeatedly, then cut from alternate sides in parallel slits that stopped just short of the opposite edge. When carefully opened, paper no larger than a schoolbook stretched into a long net-like garland. Cuts that were too shallow produced little extension; cuts that went too far broke the chain. Children often practised on scrap paper before risking the precious coloured sheet.

This craft was commonly associated with classroom decoration and festival activities in China during the 1970s and 1980s. Coloured paper was not an unlimited disposable material, so one small sheet had to create the largest possible effect. One child opened the garland while others supported it, and several lengths might be joined above the blackboard or windows. It was partly a contest and partly cooperation: one person's cutting determined the length, while several pairs of hands kept it from tearing during hanging.

Folding methods, colours and names varied between schools and regions. Some called it a la hua, or pull-out decoration; elsewhere it was simply cutting coloured paper. What made it memorable was not elaborate decoration but the discovery of structure within limited materials. Without adding any paper, a pattern of cuts and connections allowed a flat sheet to occupy far more length and space.
