The Prophets predicted that the in the era of Mashiach plants would sprout amazing things like clothes. This is how:
DNA is something that both plants and animals have in common, and that if given the proper machinery can make almost anything relative to life. The idea is to make plant DNA code in an orderly way for what we need. Could we develop plants that make shirts? – Absolutely, and especially in a controlled environment. The key would be to manipulate select plants spatially in their growth, such as the logistics of size and placement, and then also genetically alter their flower designs to get the right stuff. The way to start would be with easier weaves, and then progress to smaller and tighter fit weaves similar to the way hard discs of lower information capacity came first before smaller and smaller hardware came.
