One more picture on essential supplies for my way of designing, masking tape, (cheaper and easier to use for the cardboard than sticky tape), wire, string, tape measure and a glue stick.
I visualize by using my hands, using string, i say to myself, I want the base to be this wide, i make a loop the width i want and measure it, write it down and then move onto the next step. I want it to be this high, using string again i get the height i want, measure it and write it down. Then i say to myself, i want the waist to be this size, again using the string i make a loop. measure it and write it down. this is how i work.
