The first assignment in my Concept Development II class was to take a sport and make a small clothing collection inspired by it. I was to make 3 complete outfits in all. What was turned in were 3 boards I assembled and then presented to the class, before submitting them to the instructor.
This is the third board, the Flat board. This shows all the technical details of each garment. Where the seams are, specific placement of style lines, etc. These are left plain white so that it's clear what is going on in each garment. This is also the sort of thing you see on the back of commercial pattern packets that show what the individual garments look like.
Flats sketched on paper over a template and then scanned in and traced in Illustrator for nice clean lines. Then I put them all in Photoshop and compiled them in one image.
What I should like to change if I ever have the mind to would be to make all the flats to scale to each other so that the viewer can get an accurate idea of the size of each garment.
