Do you make this sketching mistake with your shoulder? TIP 200

Hello guys !

Today I wanna share with you a common mistake thay may damage your progress for long if you are not aware of it. You will see that it’s a very simple thing, but worth to mention.
I have received a video from Jasper who is a student of my course Sketch like the Pros. He is facing some difficulties at drawing straight lines that tend to curve. So he asked me if I could help him to fix it. Below is a screen capture of his video (the full video is at the end of this page). Can you spot the mistake ?

Can you guess why Jasper’s straight lines are curving ?

ANSWER: Jasper’s shoulder is too high when he sketches. That put him on a uncomfortable position where is elbow has a restrctive freedom of movement. Whenever Jasper tries to draw a stight line, his full arm can’t move as he would.

Rise your body posture, relax your shoulder so you can draw moving your elbow free.


HOW TO FIX: If you do this mistake as well, you have to double check your chair and table height. Your shoulder should be relax when you draw. Remember that to draw straight lines, you have to move your whole arm.

It’s a very simple thing that unfortunately affect a lot of beginners who are not aware of the importance of body posture. You can learn more about the correct sketching body posture at this article. If you wanna go further and starting sketching with the right habits, I invite you to receive the Designer Starter Kit. 

Hope it helps !
PS: Thank you Jasper for accepting to share your video with other members and all readers of the Design Sketchbook blog! 🙂
