Experiment with colours.......
Be experimental and creative with your venue décor. You don't have to be tied down by having just one colour for every chair, but could have a beautiful palette of harmonious colours that alternate each chair or are different for each table.
Other ideas could include having two sashes per chair or tying into the sash items which relate to your theme.
Tradition can be great, but we think that sometimes you need to break the mould and get creative to find something that is truly you, and your chair covers can play a big part in that.
