In addition, make sure your poster will be easily mounted with materials available. For example, foam board makes a nice, stiff back for a poster, but is difficult to mount with tacks or push pins because it is too thick. Justification of text in the center of a line will draw attention. Use bold-face, color, or special characters to draw attention. Choosing a color that does not compete with your data is wise.
Colored yarn is effective in visually linking poster elements.
Adding light color backgrounds to your figures can make the poster attractive. For example, using white lettering and lines on a blue background can make your poster eyecatching. Poster elements can also be double matted to add interesting contrast. If they are confused, it is far better to fix it now than to lose people at the meeting.
