Isabella and her brother's invitation business started from a simple family affair. One day, they decided use their talent in designing pretty things to help their family members who were planning to get married. Since then, the duo discovered the potentials of growing their business in Indonesia's bustling wedding industry. In June 2014, Signature Design was born. Most of their creations portray the wishes and requests of each customer. For the siblings, designing wedding invitations is an important step in making a dream wedding come true. "They might come from different backgrounds and have different personalities, and it is a challenge for us when these couples come to us asking for help," they said. Striving to always go beyond their capabilities, the team behind Signature Design has managed to handle the ever-growing demand and come up with fresh and creative invitation designs.
