Salvaging Old Paint

I was attempting to use some old paint for a craft, but it had lots of lumps and another can had rust dripping into my paint. I didn't have any cheesecloth to strain it with, but I discovered that two layers of tulle fastened to an old plastic container (yogurt container) with a rubber band works nicely. You could probably use another loose weave fabric as well.

And I happily tinted half of my salvaged paint using a little bottle of craft paint.
