Paint Pouring on Card

I began my paint pouring journey by creating my artworks on card. I used a combination of acrylic paint mixed with water and PVA glue. The card was unfortunately too thin for the amount of paint applied. I also found that once the paint dried it made the paper crinkle and become weak. Sometimes the liquid consistency of the paint meant it seeped through the paper onto the other side. After a few tests and discovering the above flaws I decided to move my pouring onto canvases.
