thank you for that jane and it was a pleasure teaching you!!
now back on topic.....
you dont have to do the training to be able to do the 3d work, you can indeed go it alone, and as i have seen from this board there is some excellent art work out there, but i personally would recommend it. it will give you chance to see ALL the ezflow colour collections in use, show you different tips and techniques and allow us to help you with any problems you may have.
now if your new to ezflow i would normally advise on a conversion first if you felt you needed it, just to get you used to using our product and a 2:1 l&p ratio. though if you dont want to do the conversion thats cool.
now on to the final point, mixing systems. in an ideal world you should be using either ezflow or cnd, never a mixture of both. using ezflow over the top of a cnd enhancement should be ok, hopefully the geek himself should be able to clarify this. the only time you may have a problem is when laying ezflow in a nail then capping with cnd, that i probably wouldnt do. if you are a creative affictionado, there colour powders are excellent for any type of 3d or encapsulated work and can be intermixed to create any type of colour.
i think thats answered everything!!!!
