Here is a painting tip for those who work in acrylic media. You can try this method to keep colour mixtures moist for several days. (If you own a wet palette, you can skip to the next post.)
I usually have 3 – 4 paintings in progress and tend to work with one or two colour mixtures at a time. I also have saved a collection of differently sized white plastic jar lids, in diameters of 11, 9, 7 and 5 centimetres; I am sure larger sizes can be found. Take a look at the photo below to get an idea of the set up.
I use the largest sizes for the base. Into this, squirt a bit of water. Scrape the left-over but still useful paint mixture into the smallest lid, and float that inside of the large lid within the larger lid. (photo #2). I hope that does not sound confusing.
This little paint sandwich can stay where it is, or if you have a plastic cookie container, add that alongside a wet kitchen sponge. If you have a lid that snaps over everything you can go to sleep knowing your colour mixture will be saved until your next day of painting.
