Acrylic on paper tests

Acrylic is a water soluble paint. Due to economic turmoil of the country, professional painting materials have become increasingly expensive. For this reason I decided to use low grade paper (thinner, less grams per square centimeter). It is even harder to find 220 - 300 gr paper in main cities, so these tests were made with different available papers I had. Also it has become very hard to find paint mediums like flow enhancers or paint retarders. Therefore I had to improvise and make my own retarder and flow enhancers. These tests were also made using homemade (custom) flow enhancers and retarder for acrylics.
