I'm participating in both Paint Alongs this month and so having another palette moved to the top of the list quickly. I went to my storage container, the holder of most of my stuff, to look. I remembered buying dry erase boards for a past project but wasn't sure I hadn't ditched them in one of my decluttering sessions. However, I found them!! Before I found those I found a corningware casserole that I could have used. I'm thinking all kinds of items have been pressed into service for a palette. 😁 Back to the dry erase boards - they are basically "letter" size but I cut a number of them in half for that project. I'm thinking it should be just the right size for a painting's worth of colors. And I just ordered some cheapie desktop file holders for both the palettes in the freezer and the paintings on my craft shelf. Which still needs reorganizing to reflect current projects.
