Christmas table runner - Jenny tut - Queston

[Juliadlf]

I watched this tut Make a Christmas Table Runner Using the Half-Hex Ruler | Always Great, Always Free Quilting Tutorials.

You only need 10" of print and 10" background (plus 10-12" for the border) to make the whole table runner that she is showing with 8 trees and a star? Fabric width typically 42/44 ? No transcript but a pop-up showing the materials needed. I am missing something and hopefully someone will set me straight on what she is referring to.

THANKS!
