It occurred to me that when we threw the chair cover/sashes idea out the window we never replaced it with anything. The venue's chairs are hideous, but most people here say no one will notice, so I'm not going to worry about it. I do feel that there needs to be some sort of decoration in the ceremony space (ballroom). We are renting an arch, but that will, of course, be at the front. What types of decorations did you/are you using and do you have pictures?
I may have found some tulle "bows" on Etsy that aren't too expensive. I just hate spending a lot of money for something that is going to be used for about 30 minutes.
