Hi everyone, I hope your week is going great.

I know this question has probably been asked a thousand times, but I don't the answer. Is there a website or a math formula that tells you how much fabric you need to do a quilt? For instance I am doing the Jacob's Ladder quilt for a twin bed how do I figure out how much fabric I need to do the quilt top and then the sides? I have been quilting for about a year, but I don't get to quilt that often because I work two jobs, so when I do get to quilt it is a real treat.

Any help you can give me would be great and I thank you

Debbie
