We bang on about letterpress quite a lot here at Sell! Towers. But we just can't get enough of it. There is something special, almost magical about the process. The craft involved, the smell of fresh printed ink, the texture, the little inconsistencies between each print... I could go on and on, but I'll spare you. Instead have a watch of this little gem charting the process taken by Repeat Press in producing a beautiful set of coasters for High Snobiety.
Quarter Productions have some other good videos worth a watch but if you are veggie, I'd stay away from this one.
