I've seen wheatpaste works in my city for a long time now, and I've always wondered who it was done. Today I've found some awesome pieces by street artist Nivanh Chanthara. He's got an amazing style.
Wheatpaste is a liquid adhesive made from vegetable starch and water. It has been used since ancient times for various arts and crafts such as book binding, decoupage, collage, and papier-mâché. It is also made for the purpose of adhering paper posters to walls and other surfaces (often in graffiti). Closely resembling wallpaper paste, it is often made by mixing roughly equal portions of flour and water and heating it until it thickens, or by smearing cooked rice into a paste.
For more of Nivanh's work, you may check out his portfolio. I hope you enjoy these. Cheers! ;)
