Here is my indigo vat in a 5 gallon bucket with a lid. You can see the "flower on the top of the mix so I must have done everything right. This has to be carefully pushed to one side before anything goes into the vate. I do know that it is important not to let oxygen from drips etc into the vat as that will exhaust the indigo and the vat will not longer be good for dying. Over the next few days I will post photos of the shibori and results that I achieved.
