Folding a origami paper cranes isn’t that difficult, however, folding a different origami paper cranes continuously for 1,000 days is quite impressive. For nearly three years, origami enthusiast Cristian Marianciuc continued to produce a vast flock of 1,000 paper birds. The whimsical cranes are generally more decorative rather than showing off the folding techniques. Hence, you can see from below photos that those paper birds are decorated with all manner of leaves, beads, thread, flowers, feathers, and other materials too numerous to list. Below is only a small collection of Cristian’s work and you can find all of them on his Instagram page.
