Hey so I've been shooting up for a little while now into the veins on the crooks of both my elbows and those veins seem to be pretty done...I've heard the forearms are a pretty OK place to shoot and my veins are fairly prominent there as well. I know there are some differences between those veins and the ones I've been using in my elbows (from what I've heard/observed they're deeper and more vulnerable to moving around when I try to make my shot) so I want to make sure I do it right. The number one thing I'm wondering is where do I tie the tourniquet before I take it off to shoot or do I even use it? Also, any other suggestions on shooting into the forearm? Thanks.
