These containers would be great for all sorts of craft storage! I love how they stack and hook together, but still keep things separated. And craft mats are my new best friend! This one is actually a pet bowl mat, but it has a lip around the edge which helps contain the mess! I got the 24x16. We use it for play-doh, painting, jewelry, you name it! LTKkids LTKfamily LTKhome
