Hello! We've had some questions about using the black dye and in particular how to create a deep black finish.
The simple answer to creating a dark black flower is to start with a dark red flower. Starting with a lighter coloured flower will create a a grey finish which still looks pretty cool though!
It's also important to allow the dye to fully absorb into the petals. So after dyeing it's a good idea to put the flowers into fresh water and add flower food. After a day the dye will become fully absorbed and the finish will be more intense.
Hope this bit of advice helps!
