A seamless texture will remain seamless as long as it's size is a whole number multiple of the original tile (texture not necessary to be square). Once you tile it outside of this, your result, though looks right, will no longer be seamless (i.e., if you try to tile your new result, you will get the seams).
Sorry you have the Christmas Blues Mahvin. I sort of do too. Went Christmas shopping with Dad and we had a spat since I told him you are just going to spoil your grandkids/great grandkids with all the stuff you are purchasing (guess that means I'm a Grinch; lol). Hard to be happy when you are out of work too and I've been out of a real job since February with only some occassional contract work. Heard earlier that the unemployment rate went up to 9.8%. The real number of unemployed and underemployed is around 20% but you won't hear that (I actually suspect closer to 35% but I will accept the conservative estimate). For those who still have a job, count your blessings. I do hope Congress and the Whitehouse get their act together and put the priority towards job creation and not more BS. For my overseas friends, I do hope your country is in a better situation then the pickle we are in now.
