There is lots of different coil building equipment out there. I use a screwdriver to wrap my coils. I have some wire cutters to cut the wire, but used to use nail cutters. And some scissors or those other snipping things that I don't know the name of for cutting your wick.
I don't know if stealthvape is the cheapest but it is the best for wire. [emoji106] The size and type of wire depend on what build you are doing and what resistance you are aiming for, and maybe whether you are using a mech or regulated device. I assume it's dual coils you'll be making, at a relatively low resistance? I would buy some SS wire, maybe 0.4/0.5mm. If ordering from stealthvape they also sell cotton bacon which is what I use, and you can add some free muji to your order too. [emoji2][emoji2][emoji2]
