<P> Strip folding is a combination of paper folding and paper weaving . A common example of strip folding is called the Lucky Star, also called Chinese lucky star, dream star, wishing star, or simply origami star . Another common fold is the Moravian Star which is made by strip folding in 3 - dimensional design to include 16 spikes . </P> <P> The practice and study of origami encapsulates several subjects of mathematical interest . For instance, the problem of flat - foldability (whether a crease pattern can be folded into a 2 - dimensional model) has been a topic of considerable mathematical study . </P> <P> A number of technological advances have come from insights obtained through paper folding . For example, techniques have been developed for the deployment of car airbags and stent implants from a folded position . </P> <P> The problem of rigid origami ("if we replaced the paper with sheet metal and had hinges in place of the crease lines, could we still fold the model?") has great practical importance . For example, the Miura map fold is a rigid fold that has been used to deploy large solar panel arrays for space satellites . </P>
