PixPlant looks ideal for my purposes (since it will also create the various maps for a full texture), but then I found out that it is Windows only & I'm on a Mac.............ho, hum......

Besides, both these software options are a rather expensive solution to creating one, possibly two,  seamless texture(s)!...........Might I be able to persuade one of you gentlemen to kindly work the necessary magic on two thatch photos in order to make them seamless, please?

Kind regards,

Patrice
