Why you missing so much bud? You tie off? You should try a warm compress for like 5 minutes before you stick the pin in. The warm compress will make those veins rise to just under your skin. I get a tupperware bowl full of hot water, throw my washcloth in it, slap it on the inside of my elbow for like 2 minutes, throw the cloth back in the hot water, slap that area about 4-6 times, place cloth bad on it for 3 more minutes and whamo i've got three veins to choose from.
