Working with lines

I am creating a personal stationary. I only need to add the lines. How do I creat a layer with evenly spaced lines? I can create the lines, of course, but getting several evenly spaced ones is beyond me. Anyone?

You can select the lines, and then use the Shape ▸ Align ▸ Vertical Distribute Center to have them all evenly spaced out.

Thank you! Worked perfectly.
