How is the picture frame installed?

First buy a picture frame according to the size of the work or make one yourself.

Then take a density board and match it with your photo frame.

Stick a layer of wax paper on the work and iron it with a household iron to make it smooth.

Draw a week of white latex around the MDF and stick your watercolor on it. If it is uneven, it can be placed next to the humidifier, and then humidified after gluing. Then dry it, so that the work is flat.

Of course, if it looks good, you can also add cardboard around it, which will look better.

Not to mention adding glass and installation below.
