The fun thing about this trend is that despite it being a plaid pattern, there is still a variety of colors that come in plaid and it doesn't have to be the "traditional" red, blue and white. Not to mention they could be used in a variety of places. Below are a couple of examples of where plaid can live.
Here is one place where you can put plaid fabric and it seem to be "over the top". It could be something as simple as a napkin or a table runner, or you can cover the entire table with a plain tablecloth and then using solid napkins for balance.
If you just want to add a hint of this pattern, why not send it to your guests? With the variety of shades, along with the plaid, you can pick solid variations and use them throughout the rest of the planning.
If you are that bold couple that likes to make a statement, then this option would be for you. Incorporate your plaid in the wardrobe. From the bow tie to actually bridesmaids dresses. You can go as subtle or as bold as you want.
However you choose to incorporate this bold fabric choice for your big day, make sure you do it in at way that makes YOU happy and enjoy the moment you see it all come together.
