We have a team of freelance designers who work for us, and they are paid per design that they complete. Our template monograms are designed (and priced) for quick turnaround, meaning that all the designer has to do is change out names and dates. When you want to change the font, add or remove a line of text, or otherwise alter the original appearance of the template design, it takes the designer additional time to make those changes. Even something as simple as changing the font can mean the designer has to re-format the whole design to make it look good. The modify fee is in place to cover the cost of paying the designer for their additional time.
