How to add labels to a new card based on the linked card?

[Victoria Cleary]

Here's an example of the process I want to have: 

1. Create a new card for a task (i.e. place an order for parts)

2. Link that card to the appropriate project holder card (i.e. a card called Project #1 that all task cards related to the project are linked to) 

3. Add the labels from the project card to the task card

I would like to automate the last step, but I can't figure out how to do it with lookups. Should I look to Zapier for this, or is Trello capable on its own?

Try using completion of custom fields as a trigger to do this. You will be using custom labels ie one with a name. You probably do not need Zapier to handle this.
