Hi, I already have a good level about PS and AI but i'm not sure which is the best way to do it (with the pen tool I guess) . I need to know how to design instructions like the URL http://how2assemble.com/wp-content/uploads/2013/11/Cassius-Sofa-Bed-Assembly032.jpg or http://www.trubyna.info/wp-content/uploads/2017/09/sofa-bed-assembly-nappa-assembly-instructions-how-to-assemble-how-to-assemble-ideas.jpg Thanks in advance for your help
