Choose a duffel bag in an unusual color or pattern. Duffel bags in black or gray are common, whereas zebra or polka dot designs are more unusual.
Determine the proper medium for creating a design on the duffel bag. Choose either an acrylic or fabric paint, depending on the material of the bag. You can also use fabric markers on certain materials like canvas or cloth.
Create a distinctive design on the duffel bag using the selected paint or markers and a stencil. Select a design that is large, bold and can be spotted from a distance. The design does not have to be gaudy or ostentatious, it can be simple and tasteful. For example, to customize your duffel bag paint your initials, a monogram, favorite team logo or a symbol onto the bag.
Place the design on one or both ends of the bag rather than on the top or on the compartments.
Paint the design onto the bag using paint or markers in a color that contrasts with the color or pattern of the bag. For instance, use a bright or neon colored paint on a duffel bag that is a dark, solid color. Use a dark colored paint, like purple or black, on a pastel colored duffel bag.
Make your luggage tag more noticeable by switching the white identification card with one that is custom made. Remove the white card from inside the tag holder. Use a bright colored paper or card stock to make a new identification card. Print your name and contact information in large print for easy recognition. Reattach to your bag.
Customize your duffel bag further by adding embellishments such as rhinestones, small metal studs or other accents. Place embellishments in a conspicuous location on the bag.
