So here are my tablescape mockups.  Half of the tables will have pink tulips in glass vases and the other half will have large white pillar candles in vases.  We are doing a white cardstock tablestand for the menu card at each placesetting.  The table cloths will be white too.

I am mostly trying to figure out which table number works best.  The first image is just a cardstock table stand with the number.  The second is with the number attached to the vase, either on paper or vellum.  The third is a large wooden or metal number that would lean against the vase.  The fourth is a frame on a wire that would stick out of the vase.  And the fifth is a standing metal table number holder.

Any feedback?

I like the 4th because I think it looks nice and will be easily visible for guests to find their tables.

Thanks for the input so far bees!

I talked to my mom about this earlier and she is worried that #2 won't be clear enough for people to see.  She said that with our tulip centerpieces it is likely that they will droop over by the time dinner starts, thereby obstructing the view of the number.  I hadn't thought of that at all.

She also mentioned that #2 might be tricky because we would have to attach these to the vases after they are delivered and that is just another thing, whereas most of the other options are independent of the vases. 

So that stinks because I was leaning toward number 2...
