i know i have had a lot of my a muse students asking me.. and i’ve been quite honest.. i have had tombow markers since i started stamping ( 9 years ago) and have never really tried copics……
copic has generously donated some of their markers to all the a muse instructors… so i have been playing and trying to learn…..
BUT until i can answer your questions.. linda has posted some great facts on the a muse blog here
hope this answers some of your questions for now!! 🙂
