First of all, the book is so pretty. When you take off the band, you'll see the metallic figures on the cover and a little spot where you can write in your name.
There's also text about sketching, how to represent your body type, and fashion through the decades. As always, brilliant illustrations by Sun Young Park!
When you'll get to the croquis, you might notice that they look really light. This is on purpose, as it helps you customize the figure more easily, and it also ensures that your sketching will stand out in the end, not the croquis. Make sure you have plenty of light. Use a regular or mechanical pencil, and begin to draw in the lines of your design. I decided on a dirndl, given my current obsession!
Continue the lines of the design, following the outer shaded areas of the croquis for larger proportions--and vice versa.
Add trims (like rick rack at the neckline), and sketch in the print of your fabric if desired. (The prints here are from my fabric line. Wouldn't this rose sateen be cute for a dirndl?)
If you like your design, you can sketch the back too!
Here's a better example of customizing the figure. I drew a fitted dress, giving the model a high waistline and curvy hips. She also needed some Veronica Lake hair. (I started drawing in the cherries and got bored really quickly!)
So there's a bit about using the sketchbook to draw your dream designs. I hope you'll share some of your sketches with me!
