*What do you do when your fabric dimensions are different from those required by a pattern? How do*

__you__determine the amount of fabric you will need for your project?
Recently I considered making a vintage
dress pattern. The suggested
pattern requirements were based on fabric that was 36” wide but the fabric that I wanted to use was 60”
wide.

*Surely*I would need*less*fabric since my fabric was wider...but how much fabric would I need?
Since fabric, uncut, in it's "single thickness" state, resembles a

First, I converted

*quadrilateral - a four-sided, two dimensional shape with four corners*, - I used the "*Area of a Rectangle*" Formula and the information given in the pattern, to determine the*area*of fabric that I would need for the project. Once the*area*is calculated, it can then be divided by__any__*width*to find the*length*.First, I converted

*yards to inches*so that I would be working with*one*unit of measure, in this case inches. T**.***o convert yards to inches,*__multiply__the number of yards by 36 – since there are 36 inches in each yard2 1/2 yards x 36 inches per yard = 90 inches

Once I converted the

*length*to 90 inches, I multiplied it by the

*width*of 36, to get an

*area*of 3,240 square inches. Based on the fabric dimensions given in pattern, I would need 3,240 square inches of fabric to complete the project.

Please note, rectangle is a "sketch" and not drawn to scale. |

Next, I divided the

*area*(3,240 square inches) by 60 (which was the

*width*of

*my*fabric) - to determine the

*length*of fabric that I would need for the project:

__3,240 square inches__= 54 inches long

Since we usually associate fabric length with yards, I converted 54 inches to 1 ½
yards by dividing 54 by 36.

*T***. Therefore, using this method, I calculated that I would need 1 ½ yards of 60" wide fabric to complete the project. Then it becomes a matter of pattern (pieces) placement to get the most efficient layout. Make sense?***o convert inches to yards,*__divide__the number of inches by 36 – since there are 36 inches in each yard
This is one way you can avoid purchasing (or cutting when it's from your own stash) too much or too little fabric when your fabric dimensions differ from those stated in a pattern. Hope this helps!

Until next time....PEACE AND BLESSINGS!

You still have to use common sence and not only matematics. I could make a rectangle 1 inch by 3240 inches. The area would still be 3240 square inches, but you are left with a useless and very long piece of fabric.

ReplyDeleteI find it more usefull to lay out the pattern pieces to determine how much to buy.

And on another note: I am gla we use centimeters, that saves us the hassle of converting.
