Chalk Pastels

I will be adding chalk pastels on paper to my gallery.  I am estimating that they will range from $10 + shipping and handling to $45 + shipping and handling.  I am spending less time on them than my acrylic works.   They will be in a different price bracket than my acrylics.  I am imitating my favorite artist Winslow Homer.  I read somewhere that Winslow Homer painted Oils and Water Colors and that his oils were masterpieces that he spent a great deal of time on and were considerably more expensive than his watercolors; his watercolors stand on their own as a good work, but they are less costly because of the time he put into them. So my chalk pastels will be cheaper because they are on paper not canvas as my acrylics; and because I personally will spend less time a pastel than an acrylic.  I will still sell both.
