Alyona Nickelsen recommends the following kinds of paper for use with her Brush and Pencil product range:
UArt 500, 600, 800 grit
Ampersand Museum Series Panel Pastelbord
Canson Mi-Teintes Touch Sanded Paper
Richerson's Premium Pastel Surface
Art Spectrum Colourfix Supertooth
Pastel Premier Sanded Paper
These are sanded papers which have a layer of fine abrasive grit. Originally, they were designed for pastels but can also be used for colour pencils and graphite. Depending on the paper oil, acrylic, watercolour or ink washes are possible.
To prevent Brush and Pencil's Textured and Final Fixative from cracking, the paper needs to be mounted on a rigid surface like conservation board.
Alternatively, mounted absorbent paper can be prepared by applying a layer of toothy acrylic gesso with an airbrush. For this, the gesso has to be thinned down to the consistency of milk.
