Hi to all. I made a big update (0.4) to the extension "seamless pattern". Is commited to experimental branch, or you can take from my inkspace[1] to use in 0.48 or up. Also have a you tube video inside the inkspace page.

The video has anotations but im not english so any help to improve is welcome.
