The key is that it is executed with, and a part of, the original contract. Sometimes agents confuse addendum with an amendment, which is a modification later to the terms of an already-accepted contract. It has surprised me how often experienced agents use the wrong term for a document.
At this time, wax crayons were big, dull-colored, and clumsy and were used mainly in industry. But Binney & Smith used a combination of paraffin wax and industrial pigments to create crayons that were kid-friendly. In 1903, the first yellow and green box of eight Crayola crayons appeared. (The name Crayola means oily chalk).
I will definitely look into the crayola marker thing. Most of my markers are Sharpies or Mr. Sketch. I did see a thing on pinterst where you could make liquid watercolors by soaking bunches of markers, rubberbanded together in water. But that doesnât solve the issue of what to do with the plastic part.
