Question in Preparation for My Sister's Wedding

 How does one go about finding/buying/making a chuppah?  I'm having a feeling that my sister and her fiance are not real likely to be interested in the tallis option.  I imagine that making one could also just involve some dowels with nails on top and a piece of fabric with loops, but if we did want to buy/rent one, how would we find such a thing?  If we were to make them one, does anyone have any tips? 

My parents sent me the question, and so I in turn am asking you...
