How to create multiple lines for items in an invoice

how would we achieve having multiple lines for an individual item in an invoice.

Example please

Okay..

I would just like to create some paragraphs..
I do interior finish work that requires some level of detail explaining the work and material that the client will be receiving.

If you could just hit enter, drop down a line or two and continue writing to create some separation. If I was just entering some part numbers or a small description for an item the current method of input would be fine.
