I haven't even opened the door to the pleasures of DIY juice making yet.
Would be super fun I know but my flat is pretty small. Someday!
Everything I do for Coil Making and Mixing juice is in my 5x8 desk drawers. Coil making and mixing can be done on one of those portable 18"x 24" table deals.
Can get smaller when it comes to mixing... find the juice you like, buy only the flavors for it and have a gallon or VG and 1 liter of PG. I can honestly get rid of about 30 or so flavors and be fine with what is left ( 12 or so )
All this minus the Gallon of VG/PG stuff can fit into a small tackle box or one of those 70's lunch pails. including a daedalus coil thingy
