I’ll link @MistressJennie’s comprehensive tutorial below for process info. I didn’t really lay out or preplan my designs, just winged it (wung it?).
I should also note that the “violet” (pink) one doesn’t quite represent the official process because I definitely just came in and started blithely rinsing it at the sink like (I thought) I’d seen others doing rather than asking what the next step should be . Thankfully, @Abbeeroad came by and set me on the right path . Thanks for looking!
