May 2012 Tutorial - Create Seamless Patterns in Xara Designer Pro X

[Gare]

What I did, because I didn't have loose elements, was draw my design first, just made sure to not go over the edges,
then I put rulers in place with two center guides (x and Y) with snap on selected top half, pushed bottom half up, pasted top half at the bottom, again using snap to make sure they were in the right place

did this again with left and right and then all I had left to do was connect the former outsides now in the center to make the pattern whole. created a bitmap and made an object.

then loaded my bitmap into the bitmap fill and selected tiled.

sort of an inverted 4way kaleidoscope if you will.

Cool!

I must confess that regularly I use Photoshop and its Offset command to turn an image "inside-out" and then correct any flawed parts at the center.

There's also Corel Painter's DEfine Pattern command that is great for painting freeform strokes. When you hit the edge of the window, your stroke continues at the other side of the document.

And, although these are all bitmap tiling solutions, I discovered a fun, inexpensive program ages ago called TextureMaker. It does what you call the "4 way kaleidoscope" among other things.
