I don't know what it is about a rounded corner that makes a little painting or scrap of paper cuter, but it does! This is one of my favorite parts of making my little custom palettes - rounding the corners. The last time I posted about this, there was a lot of interest so I figured I would get some in case this will bring you joy!
 
To use these simply slip the corner into the little pocket and squeeze the button! The little extra scrap will be collected underneath in an easy to empty container.
