I used vellum and printed "Table #" in a landscape format. It was cheap and super easy. There are some like it if you check out ETSY and type in Table Numbers for the search. You can do them yourself. Oh and I had them placed over a votive so they were kind of like luminarias.
Re: Rec's for table # holders?
