How do you make watercolor masking fluid?

YAY! i found a way to do it!! it's definitely a bootleg version, but it works pretty well for me so far and it's really simple to make. The only thing is that it doesn't keep very long because you have to use it before it cools. Painting on the surface after you remove it may have a different feeling, but the fairly cheap water colours I'm using work well enough.

mix:

1 table spoon clear Gelatin (no flavour)

1 table spoon milk

stir into paste in a disposable container (i use a yoghurt container lid)

Microwave for ONLY 10 seconds.

use it RIGHT way... it cools in under a minute.

apply it to the area THICKLY with a small spoon or a popsicle stick. this is probably not good for very intricate projects.

once you are done, find a thick edge and peel it off. it should come off in one big sheet of rubbery stuff!

a couple things:

you probably should test it on the surface you're using, because depending on the porousness of the media, it could be difficult to take peel off. if you want to use the same batch for the test, you can put the test in the freezer for around 20 seconds to speed the cooling.

also, make sure the thickness is consistent all the way through. the edges of the area you cover should be as thick as the centre, otherwise it could be difficult to peel off all the way
