I just came across a website that gives you free calculation sheets. There are 5 different ones.
1. Backing Calculator
2. Binding Calculator
3. Quilty Formulas
4. Cutting Strips and Squares Calculator
5. Triangles & Setting Triangles Calculator (For like HST and QST)
When you go to the website you just scroll down after each heading and it will say, "Request this free backing calculator." That was just an example. You just fill in your e-mail and name, and it is sent straight away. Do not pay attention to the blurriness of each chart shown on the webpage... it is very clear once you get the pdf in your e-mail inbox.
here is the web address :
