Quite often I’ll have to leave a paint job halfway through – annoying huh?
Well I always ‘bag’ my brushes so I don’t have to wash them or come back to solid bristles. This keeps the brush pliable and ready to use when I get back.
(put the bagged brush next to it’s pot so you know which colour it is!)
Or you could use clingfilm or freezer bags to do the same job. But don’t store them long term like this, best to clean them and let them air dry when you’re all finished.
