Surprisingly nobody has started the weekend thread yet so I'll jump in.
I tried a Cyanotype but my newish Epson home printer wont print on to acetate, so I had to use the negative directly onto the paper

Are you printing inkjet on acetate? I had mixed results depending on the brand of inkjet slide. There are some cheaper brands that don"t hold the ink very well and smear or get sticky.
The acetate is what I used in a previously in a canon printer a few years back so I know it's not that, and on the Epson website it does say
"If transparencies are not listed in the driver and plain paper + 360dpi/Text is selected, these settings are not guaranteed if the printer does not list Ink Jet Transparencies as a supported media in the 'Paper Specifications' or 'Paper Handling' section of the user guide and printer problems could arise e.g. ink on the rollers or paper feed problems."
I am using rebranded epson inks from Tescos so when they are used up, I'll try true epson ink.
