How (and When) to Stretch Your Watercolor Paper
If you work small and/or never get the paper really saturated, you can probably deal with the small amount of buckling that occurs most of the time. But, once you start painting quarter-sheet or larger, or getting the paper really saturated, stretching your paper makes your life sooooo much easier! Yes, it’s a bit challenging the first few times you do it, but well worth the lovely flat working surface.
This video shows my preferred method, stretching on the same stretcher bars used for canvas, and an alternate method for those who have difficulty operating a staple gun.
