Paint colors are the worst. I'll think to myself, "I need burnt sienna. I have burnt sienna. No worries!" Then I'll start looking and realize that I have burnt sienna in watercolor and in acrylic, but I don't have it in oil, the medium I'm currently working with. Or I'll realize that while I have five different shades of blue, none of them is quite what I'm looking for - something will be off, like I'll mix to the correct color, but it'll be the wrong transparency.
Then there's the incredible temptation to buy something new. I've already got a set of chalk pastels, so I shouldn't need to buy anymore. But I've used up of just one or two colors, and while I could buy replacements I've always wanted to try XX brand so maybe I should just buy one of their trial sets and see how it feels. But then I'll have two half-used sets of pastels instead of finishing up the ones I've got. So I should just get the individual colors I'm missing. But how often do I pastel anyway? I shouldn't spend the money.
So I pop online to Blick and drool for a while, and suddenly hours have flown by and all I've done is scatter supplies all over the floor. Little has actually been made.
My poor husband. I don't know how he puts up with all of it.
