Before you get started, work with a sheet of scrap paper to plan out your pattern design. You'll want to get a clear idea of what you're drawing before you begin. Draw a pattern that can be easily repeated. Use your colored markers to figure out how you're going to color the pattern. Once you've got a clear idea of the pattern, use the black fine tip marker to begin drawing the lines of the pattern on the bikini bottoms. Don't worry about getting the lines straight or making it look perfect. The hand-drawn quality of your design adds charm!
