I've been hard at work looking for ways to make my pins better, and I think I found it! After a week and $100 of different sealants, varnishes and what have you, I found it! Satin polyurethane(3 coats) Makes a wonderful, long lasting(and shinee) finish that's sure to protect your little friend from rain, wind, and dirt!(Just not fire, no fire please). This is the first of 5 rat themed pins I made over the past week, I'm not quite happy with the others yet, But I post these soon. I so want this to be my full time job making these things is therapeutic.
