This is a video from my Inkscape Master Class where I go over how cloned objects work in Inkscape.
Creating clones may seem similar to duplicating or copying objects, but there's a difference. Cloned objects are linked to the original object, so whatever you do to the original object will also be applied to all of the other objects. This is can get really interesting if you let your creativity get carried away.
