2b. From top bar click File, then Save As (Shift+CTRL+S), to save your file. Type the name of the file and click the Save button.






3. Select Paths Tool. Edit Mode: Design.



4. You can make picture bigger if you want, so you cut it easier. My image was at 25%, and now is 50%.


5. Start going around the area you wish to cut, by making dots.







6. If you make mistake, like on the picture below, you can use (CTRL+Z) to go back.


7. To close the selection you need to place empty dot on first white dot, you made on the beginning. Also you need to place empty square (right handle, assuming that you started from left to right to cut picture).





8. Right click on the image within the selection, from dropdown menu choose Select and then From Path (Shift+V), to replace selection with path.



8b. To have transparent background (just car), right-click on layer you are using and from drop down menu click on Add Alpha Channel.
