This is my first database-to-share. It lists knitting projects that I want to do someday. It has fields for item, description,yarn type, amount, fiber, measurements, gauge, where the pattern is, difficulty level, etc. I used to have all this in a small notebook, along with a photo, but it got too bulky and heavy to handle. There are only 4 items entered into the database to serve as an example.
