Wow, thank you. yes, I can do the mask version as I have taken the workshop (and finally have one mask version committed to memory...that is thanks to your advice of picking one thing and doing it over and over -thank you for that) and have watchd the masterclasses as well. For some reason I thought it was some kind of feathering the edge of photo to have it fade out to nothing. I believe you used it on a tag recently. yes, I just checked, it's the vole tag. I think I got it in my head that it was to do with making a selection and feathering or something. I did see a tutorial in the campus also using the eraser tool and I could have used that. It was at 1:30am and I wanted to finish and post. Today I am a zombie. Remember the days of reading a book before bed and not being able to put it down and then the next day you suffer from lack of sleep. that's me today, hahaha. Now, I have to shake the cobwebs out of my head and go do some dandelion portraits before the lawnmower gets them.
