This book on watercolor pencils is out of print, so I borrowed a library copy.
If I had bought the book, I'd probably have looked at it briefly and then put it on a shelf - to look at again later. But knowing I only have the book for a few weeks, I'm going through its pages carefully, trying to learn the techniques.
And I've discovered - in the process - that the best way to learn from an instruction book...
... is to simply sit down and practice the exercises! Learning by doing... it's the best way for some of us - though I really miss the interaction a teacher provides.
