Weekend Project: Pigment Or Non Pigment Using Masking Tape

I saw this DIY sentiment on the Scandinavian Deko site advertising their novel impress periodical Deko. This projection has a few ideas I'm interpreting.  One is to pigment a canvass striped (top image) using masking record equally a conduct as well as the other (the triangles) could purpose the same technique to practise a cool wall edge of sorts.  Then of course of report equally I piece of job out thinking, i could practise this using roughly Japanese masking record (sans the paint) as well as less permanent.  Perfect sentiment for a rental.  Tricky - simply amongst roughly thinking as well as science involved; it could endure an ace project!  If anyone attempts such an idea, delight post pictures!
