Hello, and welcome, @feldfrauen - Daniela
It is so nice to hear that you are enjoying the program. It is a wonderful gift.
Just to help you, what I have done is, I have created a ‘Master Pattern’ file which I keep. It has all of the basic pattern pieces in it, sleeve, bodice front & back, skirt, trousers, collar, cuffs, facings, openings, but only in the clean basic pattern. I draw this master pattern, using a basic multisize measurements file, so that I can check that everything resizes perfectly.
Then I load this basic pattern, rename it and start changing things so a new design. If I want to use an individuals measurements, then I load them into the pattern so that I know that it is suitable for that person.
I hope that this makes sense and that it will help you in your future patterns.
