Must the colour be fixed with PanPastel, while using chalkboard techniques?
No, a fixation is not necessary. We are useing a Versamark ink stamp pad. Versamark “binds” the PanPastel colour. Versamark is slightly sticky, it can hold the loose pigments and therefore takes the property of Fixativs. The colour pigments which are not held by the Versamark stick on the texture of the paper. Cardstock is usually even if it feels smooth, slightly structured. In this very fine structure remains a touch of pigments and reflects the effect of chalkboard. If you have any questions, please ask. I love to answer them. You can use this post for the questions.
