..screenprinting workshop

Practice time..i have an introductory screenprinting workshop to tutor this sat & sun with Impress Printmakers Brisbane & need to brush up on my screenprinting skills so ive made these drawings to experiment with.. Initially i was thinking of doing backgrounds & these line drawings over the top...i know not very adventurous but ill try layering w exposed items too & maybe a stencil????????????
Some of these lines do not appear strong on the transparency so i dont know how it will look..
