Flattening watercolor paintings 6.16.2022

When I create a watercolor painting, sometimes the paper buckles and warps, depending how much water I use in the painting. This post shows how I flatten those warped paintings.

Here you can see how my small paintings warped.
Start with a flat board or surface. I’m using a clean piece of paper, too, because I never know what scraps of drawing media might be left on the board:)
Lay the painting upside down on the clean, flat surface. These are greeting cards, and only part of the cards I painted on warped. The warped parts of the cards are what I make sure are laying upside down on the flat surface.
Spritz the back of the painting lightly with water.
Lay a clean towel over the damp paper. The towel helps soak up some of the moisture.
Place heavy books atop the towel.
I pile them about 4 books high so it’s good and heavy. Let this sit for a day.
Voila! The paper is nice and flat:)

Here’s one of the watercolor cards I flattened. You can purchase my watercolor greeting cards in my Etsy shop.

I use watercolor paint on non-watercolor paper, too, and run into the same problem of warped paper. This flattening process also works on non-watercolor paper. Just make sure to not use too much water when you spritz. Watercolor paper is thicker, and can handle more water. But spritz a thinner paper too much and the water will bleed through to the front of the painting. And now, I’ll get back to painting:)
