Everything you learn from tests, prices and suppliers is lost if you do not write it down. A library makes every collection faster, cheaper and steadier.
Give each fabric a simple code, keep the swatches in a tidy folder or box, and keep a digital copy of the pages.
After each collection update the pages: what worked? What will you not order again?
Create one spec page for your best fabric and code its swatch. Then set a monthly date to update the library.
