Hi Brynn,
I restarted using inkscape and can not find the way to merge several objects into a single one, I know Ctrl++ and Ctrl+K, but none of these do the job.
Either it deletes nearly all, or the white object disappears..
I post you another pic of my first illustration with inkscape.
If you haven't seen the movie 'Zombilenium', you 'll like it, it is made from a comic done on illustrator(nobody is perfect)
Cheers,
Gauthier
