I`m about to make an order from B&S to try some VDB , but want some input on what I`m ordering, as I`m totally new to this. So far in my shopping cart I have: A premixed VDP-kit Puddle Pusher coating rod (I can use the 8x10 rod for 4x5 and 5x7, right?) 100 sheets of 8x10 Cranes Kid paper. Anything else I need to get started? Any additional chemistry to control contrast etc...? I have a contact printng frame.
