P.S. carpet tape (double sided) is very useful for keeping the plate in place during inking and printing (though it bends a lot when you try and remove it). My favourite “baren” is a wooden spoon and a bit of “nose oil”.
Thank you for the detailed response! I will definitely look into getting some carpet tape and pins. I've told myself that I have to use up all my water based ink before I can invest in safe wash ink, but depending on where I can find it I might snag it during Black Friday sales.
