We've used these banners for making our own designs to stand out in a crowd of political demonstrators. The triangular shape is easy to spot in distant, large group photos. The size and shape work well in no breeze through moderately high wind conditions. They are light enough for a ten year old to carry and tall enough to be above heads without being ungainly.Permanent FABRIC Markers worked the best for adding color. They've done well in snow and drizzle; haven't had them out in pouring rain yet.Over all, I've found these to be the best choice for a large, bright, eye-catching message large parade crowds.
