Sewing Two Table Cloths Together?

I have two table cloths that I would like to piece into a double-sided table runner (they are too short for my table). I am a seriously novice sewer, so I am not sure how to sew the edges together to make it neat, or if I should use a binding like cord. Also, because of the two fabrics, should I put quilt batting inside to retain shape?

One side will be "visa" fabric in ivory, and the other is a cotton (india) print; rust color with ivory reindeer. I may put a floral embroidery patch (not handmade!) on the ivory side to use during non-holiday months or in spring/summer.

Thanks!
