I want to tile this as a pattern, if I follow the traditional off-set routine I will destroy the clean pattern as so commonly found on pages such as; this. I'm hoping someone can help ? Probably another way, I once again have forgot
Use the Marquee tool to drag out a rectangle with opposite corners touching similar features of each element. In the case of the above image, this would be about 545 pixels square. Crop, and then do the Offset technique.
If you don't need the variation, you could just use a fixed-size Marquee of 91 pixels square, placed so it only covers "Unvaried" elements, and then Edit > Define Pattern.
You said draw a marquee that is 91px then define pattern, that is what I did. On a new canvas "edit > fill" there are seams in the fill. Post #4 demostrates this.
The seams you show in reply #4 look like you're using Offset filter after already seamlessly filling a layer with 91 x 91 px tiles. If you are, then why? If you are not then post a screenshot of the Edit > Fill dialog containing the pattern tile just before pressing OK.
I make a marquee and I enter in 91 x 91px the results are still not what I want. How are you getting this 91px how are you able to get a perfect seamless tile, I've read this thread a few times and my results are not your results.
