W: Art Department. This is Brown speaking.
M: Hello, Prof. Brown. My name is Frank Meloy. (22) I’m thinking of taking your course in Synthetic Fiber Painting, and I’m calling to find more about it.
W: Have you ever worked with synthetic fiber paints?
M: I’ve done very little painting. I’m a Chemistry major, but I enjoy drawing and the course description says that any student can sign up. I assume that means the experience in painting isn’t necessary.
W: Yes, that’s right. (23)We’ll be using synthetic fiber paints instead of oils because they dry more quickly. Also, beginning students can get a good feel for what they can do with textures by working with synthetic fiber paints.
M: My roommate is also a Chemistry major but he has painted quite a bit. If he signed up for the course, would he find it too easy?
W: No, (24) he could work on using techniques he already knows and applying them to principles of composition, colour and design. There’s something for everyone in this course.
M: One more question: Do we need to bring our own brushes and paints to class?
W: Yes, you can buy them at the bookstore. I’ll provide drawing board and any other supplies that are necessary. I hope you decide to join us.
M: It sounds interesting. I’ll definitely register. What are your work hours?
W: Fine. You can enroll in anytime from 8 a. m. to 5 p. m. (25)I am looking forward to your participation and I hope to see you next Monday afternoon.
