hi all
sorry to be a pain but i need some urgent advise on how to tie dye using the washing machine method.
i have bought some dye powder from a specialist company which they worked out how much i needed by the weight of my fabric. i have the right amount of salt and soda crystals
the problem is i have done some tests in my washing machine and none of the results give a nice pattern!

there seems not to be enough "white" on any of them
is this because im not using the "washing machine process" and not another process like the dipping the prepared t-shirt into a solution as the washing machine method allows too much of the dye to soak in?
i have 30 thirty t-shirts to do today or in the next day or two for a hockey tournament and desperate for some advise
all i want to do is a marble effect

many, may thanks in advance
alex
