Hopefully you have finished your candle mat, and if so email me a photo...I'd love to post it for you!
Today for your runner, you need to take your little pieced rectangles and divide them in half. Sew half of them into squares as before:
Then make a nice pile of the other (matching) halves:
We will use this pile on a pieced border.
When finished, you should have 12 pieced squares, and your 12 uncut squares that you picked out in the beginning.
Talk to you soon!
