I hesitated splurging on a color chart for years. I own more Unison than any other pastel, and over the years I have tried to fill in values or hues I was missing by looking at swatches on my IPad. The sticks that came we’re not always what I was expecting and I’m sure I have spent more money on pastels I seldom use than a color chart costs. The beautiful color chart I just received is going to make both filling in my set and selecting my pallets for painting way easier! Thank you so much! This is an excellent product and well worth the investment. The only problem is, I have quite a few TL, Great American, Schminke, Sennelier, …hmmm......
