Flats: Technical Drawing for Fashion, second edition: A Complete Guide

I learnt to do them in Illustrator in Fashion School, but as many people have said any vector program could be useful. I really love this kind of drawings because I've never considered myself a good illustrator and this is something I can do really well. In Spanish we call them "technical drawings" but it seems in English in common to call them "flat sketches" or just "flats" There's some good books out there about the theme too. I was doing a quick search in amazon because the ones I have are in Spanish: https://www.amazon.com/-/es/Flats-Technical-Drawing-Fashion-Complete/dp/1780678371/ https://www.amazon.com/-/es/How-Draw-Fashion-Flats-techniques/dp/0984356029/ https://www.amazon.com/Fashion-Flats-Technical-Drawing-Bundle/dp/1501313037 https://www.amazon.com/-/es/Flats-Technical-Drawing-Basia-Szkutnicka/dp/1856696189/ I hope this helps you! For me this is one of the more enjoyable parts of fashion design (just because I'm a little of a math nerd and love making patterns and technical things) =D
