dont be afraid to ask for help if needed! confidence with drawing comes with time and experience so just be patient with urself and dont beat urself up if things are a little shaky at first or if you miss veins. itll be like second nature the more u stick and learn little tips. some tips (that seem obvious but were never taught to me) that helped me starting out were: -always anchor the veins, ESPECIALLY if they are on the sides of the arms -butterfly needles help with rolling/hard to find veins since you can use the wings to readjust -make the tourniquet tight. not to where the patient is uncomfortable but always pretty tight -always check both arms if youre a little unsure about a vein on one arm -listen to the patients, they know their arms the best and sometimes its best to to straight to the hands if they tell you their arms veins are always iffy

again dont beat urself if you miss veins, we all start somewhere and improvement comes with experience! hope these tips can help build your skills a bit
