Posca pens contain water-based acrylic paint — opaque, vibrant, and permanent on porous surfaces — in a marker format that works across an extraordinary range of surfaces from paper and canvas to rock, wood, glass, ceramic, plastic, and fabric. In this complete guide we cover the full range we stock at Craft and Canvas: every nib size from the ultra-fine PC-1MR at £4.99 through the broad PC-17K chisel at £9.49, the standard, fluorescent, metallic, and glitter finishes, how to prime and use the markers correctly, how layering and blending work, what surfaces suit which size, and which pens to start with depending on what you want to make.

Gouache sits between watercolour and acrylic — water-based and brush-applied, opaque and layerable, with a distinctive matte finish that neither medium replicates. It can be painted light over dark, used on black paper, corrected by painting over mistakes, and reworked once dry. In this complete guide we cover what gouache actually is, how it differs from watercolour and acrylic, what it excels at, and the full range we stock — from the Seawhite Starter Set at £6.99 to professional Sennelier Artist Gouache at £24.95 for 100ml. All at Craft and Canvas, Hebden Bridge.

Montana GOLD is not conventional spray paint — it is a low-pressure, NC-acrylic lacquer developed with professional graffiti and mural artists in Germany, available in over 200 lightfast colours, and precise enough for detailed studio work as well as large-scale murals. In this complete guide we cover what makes Montana GOLD different from standard aerosols, the colour range categories, the Level Cap interchangeable nozzle system, the wide range of surfaces it works on, how to apply it correctly, and the Montana Acrylic Markers that extend the system into detailed mark-making. Montana GOLD from £9.95, Level Cap Set 1-6 at £3.99 at Craft and Canvas.
