Some sketching and painting notepads have the paper glued together on all four sides of the notepad. This makes sure that the paper stays in place when you sketch/paint. Given that I love the paper of Clairefontaine notepads and that they do not offer their pads as sketching/painting notepads, I tried to modify one of their normal spiral bound notepads this way.
I opened the cover and carefully applied glue (“Uhu(R) Kraft”) to the sides of the notepad. One side at a time and let it dry overnight. It worked perfectly — the paper got a little uneven, but only minimally. The liquid adhesive dried and did not become sticky anymore. In retrospect I should have left (part of) one side unglued to make it easier to remove a page.
But it’s a nice way to get a sketching/painting notepad with the paper you love.
