Hi dear, can we do this in Canva?

That's really helpful, thank you very much! :)

I have two questions.

My Inkscape border is black and I don’t know how to change it two white.

Also I had an image of a dog with a window in the background and I outlined that little dog 12-15 times and no matter what I tried the dog kept getting deleted instead of the background. I couldn’t figure out how that kept happening. I don’t know what I need to change so I’m able to keep the dog and get rid of the window.
