Tileable Patterns with GIMP

This post is for people trying to create tile able patterns using Gimp

Let's start with an openclipart symbol
http://openclipart.org/detail/1634/clothes-iron-by-johnny_automatic

Open this svg file in Gimp - resize it to 400x314 pixels
goto Layer / scale and put 200x157 pixels
duplicate this layer
On the 1st layer goto Transform / Flip Horizontal
On the 2nd layer - select layer to image size
then goto Transform /offset then click on the Offset by x/2, y/2 button and click on the Wrap Around radio button
The result should be :

Now select copy visible / and paste as pattern

you can now create a new image 1600x1200 pixels with a dark background
and fill that image with the above pattern

The result will look like this :

Oh ?! you wanted an "Iron man 3 wallpaper" ?!
