Recently, I had the fun of teaching marker techniques, using the professional Touch Twin art markers made by ShinHan and distributed by Close To My Heart.
These are fantastic markers that have been designed for the vibrancy and consistency of their colors. Frankly, because of that intent -- and ShinHan's primary market in Anime art -- these markers don't blend as well as Copic markers, in my opinion, and require a different technique than I learned in Copic Certification classes.
I'd love to teach these techniques to you! Can we schedule a workshop?
I colored this cute koala in the class, and recently turned it into a card:
Supplies used: Close To My Heart's "Cute Koalas" stamp set (D1642, $17.95), Memento Tuxedo Black stamp ink, ShinHan Touch Twin markers, leaves cut from a Silhouette Online store and applied with Bonding Memories (CTMH) glue; mounted on Black and Glacier cardstocks. Sentiment stamp by CTMH.
