To support herself and her son, Bette worked as a secretary, developing her typing skills. She also pursued her interest in art, painting Christmas window displays for a local bank. This combination of skills would later prove invaluable.

Bette secured a position as a secretary at Texas Bank and Trust in Dallas, Texas. This job provided her with a stable income and a platform to observe and address workplace challenges.

Frustrated with the limitations of existing methods for correcting typing errors, Bette drew upon her artistic background and began experimenting with paint to create a correction fluid. She initially called it 'Mistake Out'.

Bette began producing Mistake Out in her kitchen, using her blender. She initially distributed the product to her fellow secretaries and acquaintances. This grassroots approach laid the foundation for her future success.

As word of mouth spread, the demand for Mistake Out grew. Bette expanded her production and began to sell the product more widely. She continued to work at the bank while building her business.

Bette was fired from Texas Bank and Trust for accidently putting the company's name on her product. She devoted herself fully to the production of Liquid Paper.

The 1960s marked a period of significant growth for Liquid Paper Corporation. Bette refined her manufacturing processes, expanded her distribution network, and faced the challenges of managing a rapidly growing business.

Liquid Paper became a household name, with national and international distribution. The company experienced continued success, and Bette became a successful businesswoman and philanthropist.

Bette Nesmith Graham sold Liquid Paper to the Gillette Corporation for $47.5 million plus royalties. This marked the culmination of her entrepreneurial journey and solidified her legacy as an inventor and businesswoman.
