I chose sweetpeas as these were the flowers at their wedding and in my Grandma's bouquet. The little teacup is detachable so that invited guests can simply fill it out and return it to my Grandparents - and can then keep the invitation as a reminder of the date and time. Overall I feel pleased with the finished product, I would have liked the writing so be a little more elaborate and decorative, but as the majority of the invited guests will be elderly, I felt it needed to be clear and easy to read.
Happy Birthday Grandma and congratulations on your 60th Wedding anniversary!
