The Truesizer app provides a simple mechanism to assign threads from standard charts or custom thread collections to your designs.
Thread charts
Thread charts are predefined sets of embroidery thread colors from various manufacturers. They contain colors and codes that match real-world embroidery threads used in production.
Thread collections
Thread collections are sets of threads derived from standard thread charts or created as custom colors. Thread collections may include threads from one or more thread charts. They are usually made for use with specific designs or customers. For instance, if a particular manufacturer uses a specific range of threads, you may set up a thread collection for that customer.
