I detached green sticky tapes which were used to attach poster or advertisement materials from buildings wall.
I leave tapes as it was. I did't re-arrange green tapes position. and I make patterns with green tapes and their position. After detaching green tapes and making patterns, I designed T-shirts with those patterns.
Pictures below are the pattern book.
I wrote the address where I get patterns at the each patterns first page.
and paper with colorful pattern is designed for some kind of origami paper.
( I uploaded just a few pages :) )
