How to flatten drafting mat.

Pull the razor slowly and steadily towards you stopping at the bottom corner. Then run your hands over it to make sure there are no bumps lumps or other flaws to telegraph through. This will soften it down and then you can try setting something heavy on it to get it to retain its flat surface. Once the item is wrapped around the tube image facing out place rubber bands around it so it won t unravel.

Place your mat on a smooth flat surface outside in the sun on a warm sunny day until it flattens check it every 15 minutes. But i think there is a solution here this might seem counter intuitive but one way to get a mat to lay flat again is to add back a little heat. Check the mat s flatness and then repeat the process if necessary until the mat is flat. Remove the paper backing from one of the strips and place it in the top corner vertical with the sticky side up.

Use a straight edge razor to cut the backing and mat boards. Keep doing it until entire mat is flat and covered with heavy books. Creating this opposing new curl shape will in effect straighten the curled plastic. Now roll your mat back out.

Make your first hinge. Leave the mat between the metal sheets until they return to room temperature. Next roll your map or poster around the tube with the image facing out. What about heating areas with a hair dryer and while it s still warm plop some heavy books on it.

Not what you want to have happen to your expensive cutting mats. The length of the strips depends on the size of your artwork.

I was careful that the mat didn t get too warm. Cut 4 strips of self adhesive linen hinging tape. Then flip it over and reroll the mat. Even if you think your floor is clean sweep it one more time.

If your paper is less than 30 inches 1 4 inches is typically fine. Keep the same pressure throughout your cut and be very careful not to dip out or in from the penciled line. I was able to straighten it flat again by laying the mat on a towel on a table covering it with another towel then using a steam iron on the lowest temperature at which it would still steam ironed over the towel and mat. Fight curl with curl unroll the mat as flat as you can get it.
