Review on 🎨 AUREUO Mini Stretched Canvas: 3x3 Inch/24 Pack for Kids - Ideal for Painting & Craft Projects by Karla Richter

These tarpaulins are loose but easily repaired. Using any spray bottle, spray water on the BACK of the curtain (the area that is accessible inside the frame) and lay on the curtain walls to dry. The fabric stretches as it dries. It's not perfect, but it makes them so much better. If you find that the surface is rough (that's what happens when you work with fine detail!), buy a cheap gesso, paint it with a cheap brush and sand it lightly with 240 grit sandpaper. Alternatively, just wear Apply a thin layer of Titanium White (or any background color of your choice) and let it dry completely before painting your masterpiece.
