|I've had a renewed interest in fitting so I have been relearning the basics by researching new and old fitting books/guides.
Although I do flat pattern adjustments to begin with, I love draping the fabric and find that it is easier and it's accurate to fit this way, although, all garments during the sewing process still need to be tweeked as you sew.
Yes, fittings are a BORE and are tedious and NO ONE likes doing them but this is what sets masterpieces apart from the ordinary.
The Slash method, where one cuts the muslin open to make a needed adjustment which is done by adding fabric or by removing it, is a method I rarely see in books.
Yes, it's extremely time consuming but there are seamstresses who sew at this level of expertise. This info is for those interested in "as-close-to-perfection" as one can get.
Here is a web page that demonstrates this technique beautifully
It is from 1963 and it is shown using coats .
If you read through this carefully, you will also learn to interpret what wrinkles or pulls mean and the solutions.
I know you will enjoy it.
