"..I have painted a few studies of the figure.. .I send you [Theo] two sketches. The painting of the figure appeals to me very much, but it must ripen - I must learn to know the technique better - that which is sometimes called "la cuisine de l'art". In the beginning I shall have to do much scraping, and often to begin anew, but I feel that I learned from it and that gives me a new fresh view on the things."
