Yeah I'm looking into workshops, just feels tricky to find a good fit sometimes! But yes, either way I am keeping in mind I can ask my previous manager if I need to - I think on my list of schools, only Johns Hopkins doesn't mention an employer as a potential reference, so I may reach out to the admissions office and see if that's allowed. My job isn't in the arts but they'll be able to speak to my ability to collaborate, my work ethic etc. Thanks
And @shadygrove thanks for the advice - I did reach out to one of them 2 years ago as a reference for a job and he was really responsive, so hoping for the best. Good luck with your professors!
