Last Mission
If you:
1. need to do a small painting;
2. don't want to use a brush to avoid cleaning it;
3. have an empty can and a used kitchen sponge that you were going to discard;
4. have a metal cutting scissors, a general-purpose scissors, and instant glue; and
5. Appreciate reusing materials rather than discarding them.
So I have the following suggestion:
Make small brushes for your paintings.
Materials and Tools
Disposable materials: empty can and used kitchen sponge.
Tools: tin cutting scissors, general-purpose scissors, and instant glue tube.
Cut
Cut the can, mark the brush shape, and cut the sponge to the appropriate size and shape for its use.
Fold the sides of the handle to avoid cutting yourself with the can and to provide better support for the handle.
Gluing, Using, and Reserving Sponges for Future Use.
Glue the sponge with just a few drops of instant glue.
If necessary, you can bend the brush to fit the surface that will be painted.
You can produce different sizes of brushes.
Once you finish painting, simply remove the sponge impregnated with paint and glue a new one in its place.
That's it.
Thank you for reading, and I hope I've motivated, inspired, and guided you.
