loose the wood stain and artline.
i got a simmilar ink recipe i posted earlyer bit ive changed it a bit..--
60%nero d'inferno black
10%nero d'inferno red
15%corio pirple
15%feibings pirple
boil it up till its a bit thicker,dont let it boil rapidly or on a high flame tho or it might catch fire. ad some more corio and feibings to thin it a bit, put about 1 or 2 grams of gentian violet crystals to 100ml of ink., mix well, fill a marker and write on your local transit system. the more feibings or corio you thin it with, the more drips.
i put a bit of brake fluid and a bit of fish oil in now too.
