I have to watch my spending now more than ever before. One thing I use a lot of is glue. If there is a project I am making that needs to be painted and has a surface that paint does not usually cover well, my go to is covering the surface with a one ply layer of a napkin. This requires Mod Podge. It is not cheap, so I make my own. All you need is regular (dollar store) white school glue. Take one cup of glue and add 1/3 cup of water. Works for me!
