Crop fabric photos for use as tile pattern

I have about 160 photos of fabrics, that have already been color corrected.

I need each photo cropped carefully so that when repeated X and Y, it looks the same as the original larger image. This is to be used as a website background wallpaper, or in 3D software. Examples attached.

You may have to also rotate and perspective correct the image before cropping to straighten the lines.

Do not resize/scale the image - it is important that the sizing stays consistent to represent accurately the original scale of the real fabric pattern.

When doing it myself, I spent about 7 minutes per photo.
