Today I learned about construction a little bit

I got curious and started asking a whole bunch of questions. One of my questions was about how the patterns get put onto ceilings and walls. I learned that there is a paint that you can spray onto walls that will make the pattern become how it is. I also learned that it can be done with sponges and knives. I learned that the pattern on the ceiling can often times be done by a mop. They will push the mop up on the ceiling a whole bunch in order to get it to make a pattern that is constant. I thought it was pretty interesting.
