The Knitting Yarn Calculator is a tool for knitters. It helps you determine how much yarn you will need to buy to make a standard drop sleeve sweater based on the gauge and measurements that you enter. You enter your desired chest measurement, your stitch gauge and hit the calculate button. It will display how much yarn you need to make that size sweater. You can customize the application under the settings tab. This allows you to choose between entering stitches per inch or per ten centimeters for gauge, entering the chest circumference in inches or in centimeters, and you can also choose to display the result as yardage required or as meters required.

The second part of this application is the Project Inspiration tab. Not sure what you should make for your next project? Have a color in mind but not sure what fiber to use? Just want to have fun spinning some wheels and daydreaming about all those fabulous projects you would love to make? The Project Inspiration tab has three wheels which you can spin independently to get a random result: the first is a list of colors, the second is a list of fibers and the third is a list of project types. You can even shake it to get a completely random result. Blue merino hat anyone?
