Awesome deal, but my question would be can you find the right shade of brown in that same fabric or can you buy extra of these panels?

That's what I was thinking, to buy extra of the panels and use the base for the additional length. You cannot find a price like that for a good yard of fabric! You can probably do three or four curtains out of one panel, plus the edges are already done for you. ;)

Thank you so much for the replies! You are spot on with what i was thinking, which was to just buy extra panels (in dark brown) and use that as my add on fabric. Should i do same color fabric or do the dark brown? (like the penneys curtains)

Oh, that would be great! Use either color. Keep in mind that using the same color will visually lengthen the curtain and the room, though. Depends on the look you are going for.

I would do the same color fabric so that the seam is less noticeable.

I'm with nhb that either would work. I'd go same color to add height to the room if it were my choice. I think you already have enough going on at the bottom of the panels without adding another color. In fact I'd remove the hem which appears to be an add on and use the solid to lengthen and hem each panel.

That's what I'd do, too! Remove that wide hem, and start from fresh at the white trim.
