What you'll need:
Painting surface (don't use paper as when I did it wasn't too much success , cloth, canvas, or even walls!)
And some CREATIVITY!!
You can normally find all of these materials in your closet. (Subjective)
Where to buy:
Local diy store
How much time:
Less than you think (approx. 5-10 min)
A painting with strips of white spaces
Step 1: Design and Sketch
This may be a crucial element when doing paintings but with this technique it should not take you more than 2 minutes. Take a pencil, ruler and your painting surface. Wherever you draw lines will be where a strip of white space will be (and where you will stick the duct tape). Draw straight lines on your page according to where you want straight lines.
Don't spend too much time on this
Step 2: Stick the Duct Tape
The title explains it all. Stick the duct tape on your straight lines on your painting surface.
Make sure there are no air bubbles
Step 3: Paint!
Now comes the exiting part. Take your paint and paint brush and fill the whole page with paint.
Use 3 or less colors
Step 4: Remove
Now you can remove the duct tape of the painting surface and admire the painting. I do not have any photos when the tape is off because I used paper and when the tape was removed the paper peeled off with it but I am sure it will work with cloth or canvas because I've tried it before. And also use the tip of using paper.
Remove softly to avoid surface coming off with it
