Why 141mm Square you ask, that's rather specific? Well this pre-cut cardstock size is the perfect size to print onto then mount onto our 147mm Square cardstocks giving a perfectly sized little border and added 'weight' to a flatboard invitation or invitation element. Of course the 147mm Square cardstock fits perfectly into our 155mm envelopes so this little gem, (the 141mm square,) is the start to your layered flatboard day invitations, evening invitations, menu cards, table name or number cards....all sorts of stationery items! We always say, "start with the envelope and work backwards" which is why our Enfolio elements are so carefully considered and sized accordingly. If you wish for a contrast simply choose one of our many, many A4 boardstocks (coloured, lustrous, sparkly) and cut the 147mm squares yourself then mount the 141mm square boardstock on top!
