how to group and copy

[coachswife]

I made an image that I would like to copy and then flip and weld together so that both sides are the same. How do I do that? I just can't figure out how to group it or select all of it and then copy and paste it.

never mind, I figured out what I wanted to do. Now if I can figure out how to post here I'll share the file!
