WHAT IS A SEAMLESS TILE:
A SEAMLESS TILE IS A REGULAR SQUARE TILE...HAVING THE POSSIBILITY OF TO BE PASTED VERTICALLY OR HORIZONTALLY ....USING AN IMAGE EDITING PROGRAM LIKE GIMP, PHOTOSHOP, ETC.......WITHOUT LET THE "SEAM LINE" VISIBLE.
Another way to use a seamless tile is to "fill" a vector shape, design..... using MTC, SCAL, SILHOUETTE STUDIO,FUNTIME, ETC....and then printing it and finally cutting it to use on a project.
You can search the web for a TUTORIAL showing how to do it. Sorry but my horrible English doesn't let me dare to write that.
