Pinterest is an inspiration engine. It is designed to keep you scrolling, dreaming, and discovering. It is NOT designed to help you buy, build, or cook.
Inspiration is vague. Execution is specific. Inspiration is 'Modern Kitchen.' Execution is 'IKEA Voxtorp Cabinets in Matte White, 24-inch width.'
Notes are the bridge. They allow you to layer execution details on top of inspiration images. You can link to the actual product page, write down the price, or list the tools you need.
Without notes, you are stuck in the dream phase. With notes, you have a plan.
