Do you now what Inkscape is? OK. Probably, most of you know, but for some of you who don’t, it’s free Open Source Software for vectors. I like vectors, for me it is so exciting that combine vectors with HTML and CSS.
I made a little tutorial how to create vector clip in Inkscape.

Step 1

Open Inscape, click on File > Document properties (or CTRL + Shift +D). In section Orientation set for Landskape. You specify dimensions.
