hi guys just thought i would throw my 2cents worth in. its not the die but the method of use that needs practice the dies in of any ones make be it solvent based or water based need working with and they use different methods of application. i have seen great results with both dies, not in my work but in others who have put in the work with them. i use the spirit based because that's what i learned on. but that does not mean i cant get the same results with the water ones just need to practice with them.
