Everyone will have their own methods, but I always appreciate hearing alternative ways to accomplish a task as different approaches can suit different people’s workflow, especially if one is comfortable/proficient in Photoshop and can bring that skillset to SU?
By example of the offset method, here are a few random ones I did using the “offset” method (no more than a few minutes for each). Like with any “seamless” texture, the difficulty is to try and reduce repetition. For the B&W linework that’s not an issue. for photographic brick/wood it would mean capturing a wider sample, or just use the wider example by itself if it fits, or you can expand its size/variation using some cloning techniques in PS. For a photo-real rendering the randomness of textures is critical, but for the OP’s needs as a graphic for a construction document it may be less necessary?
The “texture generator” that Mike mentions is a great solution too, I hadn’t seen that before, and will surely use in the future.
