I'm working on cleaning up some typical materials and have a potentially dumb question -

When creating simple repeating patterns like a Soldier Course - how big should the image be? Barring an extremely colorful brick pattern the image could technically be one brick wide plus mortar. The only thing I'm not sure about is how that will affect performance. Will having to tile the pattern 20 times per header be detrimental to overall performance versus using a material that is roughly the same length as a typical header (say 48")?

In a field pattern I can understand using a larger image to help break up the tiling effect but is it really necessary for a small sample?
