Editing existing design

I'm new to Hatch (love it!) and going through videos. But need to edit existing design for a client. Could someone direct me to the best video for editing existing designs? 

Hello,
There are several videos in Hatch Academy that use editing as you use this often.  However, to focus on editing look at these:

In the Getting Started have a look at GS-14 - Customizing and Editing Designs  Lessons 14-01 and 14-02
TE-10 has 17 video lessons on various editing existing design capabilities.  These are in the Gold Pass.
