Infinity has no end. Infinity is the idea of something that has no end. In our world we don't have anything like it. So we imagine traveling on and on, trying hard to get there, but that is not actually infinity. So don't think like that (it just hurts your brain!). Just think endless, or boundless.
Example of a court card, postmarked 1899, showing Robert Burns and his cottage and monument in Ayr. A postcard or post card is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. Shapes other than rectangular may also be used. There are novelty exceptions, such as wood postcards, made of thin wood, and copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut postcards from tropical islands.
Here is a good way to recycle used paper and make a beautiful greeting card for someone special. Make your own artsy paper that has wildflower seeds in it! Use colored markers to paint a design or message on it. Give it to someone special to plant in a pot or in the ground.
