Girls Blazer Basic Pattern Calculator - 7-14 Years

Learning how to make your own pattern has never been easier! If you want to become a true pattern maker without spending a lot of money on beginners sewing courses then you are in the right place. Buying or downloading a free baby pattern never offers you the perfect pattern for your body. Doesn't matter if you are a beginner or not, my 'Girls Blazer Block Calculator', complete with step-by-step instructions and a detailed drawing will help ensure your quick success.
The girls blazer pattern calculator can be used for 2 age groups 7-10 years old (122-140cm tall) and 11-13/14 years old (146-164cm tall).
The girls blazer block allows you to create any designs you want.
The jacket block is constructed to reflect the changing shape of girls from the age of seven.

Instructions for using the pattern calculator:
* Add your measurements in the yellow cells from the "MEASUREMENTS" tab. The basic measurements needed for the pattern should be made by using the sketch from the same sheet and the measurement code (ex. A, B, C, etc.)
* Press button "Calculate"
* In the "RESULTS/INSTRUCTIONS" tab, the dimensions for the blocks will be computed automatically.
By following the steps from "RESULTS/INSTRUCTIONS" and the drawing you will be easily able to make your own pattern. Good luck!
