When I was last in a Dollar Tree, I noticed that their "posterboard" would probably be an excellent substitute for oaktag, though it might be a tad thinner. And it comes in plain, easy-to-write-on white. I've no clue, however, as to how it would age. Papers bleached to white are often high acid.
Posterboard is a popular and affordable alternative to oaktag, which is a heavier and more expensive cardstock. Dollar Tree's posterboard is indeed thinner than oaktag, but it still offers a solid surface for writing, drawing, or printing. It comes in a plain white color that can easily be decorated with markers, paints, or other art materials.
One thing to keep in mind about posterboard is its acid content. High acid content in paper can cause it to yellow and become brittle over time. While Dollar Tree's posterboard may have some acid content, it's important to store it properly to ensure it lasts as long as possible. Keeping it away from direct sunlight, high humidity, and extreme temperature changes can help prevent deterioration.
In conclusion, posterboard from Dollar Tree is a great substitute for oaktag if you're looking for a budget-friendly alternative. However, it's important to be mindful of its potential acid content and take steps to store it properly.
