Wedding signs can cost anywhere from $25 to $300 or more. For example you can order table name tags in acrylic for a little over $1, but if you ordered that same acrylic sign in a 36" x 48", it's going to be about $240. The key is to know how much money to spend on which product and in what size. You can get that same 36" x 48" sign in foamboard for only $95 and it will still look amazing!
