How to rescue water-damaged gouache paintings using absorbent blotting, rehydration and conservation adhesives

Water damage to a gouache painting can feel like a small disaster — colours that bled, paper cockled, edges that softened into a muddy haze. I’ve had my fair share of chilly mornings in the studio when a cup tipped, or a storage envelope let in damp during transport. Over time I’ve developed...

How to build a portable mixed-media kit for train or café sketching that survives spills and tight spaces

How to build a portable mixed-media kit for train or café sketching that survives spills and tight spaces

I’ve spent years refining a compact mixed-media kit that fits comfortably under a café table, in a train seat pocket, or on my lap without turning a brief sketching session into a logistical puzzle. The trick isn’t just squeezing supplies into a small bag — it’s designing a system that protects fragile materials from spills, keeps inks and wet media tidy, and gives you enough variety to...

How to rescue cracked collage layers: step-by-step fixes and when to use pva, golden gel or conservation glue

How to rescue cracked collage layers: step-by-step fixes and when to use pva, golden gel or conservation glue

There’s nothing quite like the sinking feeling when you lift a flap of collage and find brittle, cracked layers beneath — torn paper revealing white gashes, flaking paint, or adhesive failures that threaten the whole piece. I’ve walked into my studio to find a finished panel with a cracked collage layer after a hot weekend, or spotted tiny fissures spread across a layered work made years...

What to photograph first when preparing images for giclee printing: capture, edit and export checklist for consistent colour reproduction

When I prepare images of my paintings and mixed-media pieces for giclée printing, I try to think like both the maker and the reproducer. I want the texture, colour relationships and subtle marks to survive the translation from studio surface to archival print. Over the years I’ve developed a practical checklist that starts in the studio and ends with an exported file that a print lab can...

techniques to add intentional 'mistakes' that enhance narrative in figurative work

techniques to add intentional 'mistakes' that enhance narrative in figurative work

I often think of “mistakes” in the studio as conversations my work invites me to have, rather than problems to be solved. Intentionally introducing slips, glitches and unexpected marks can open narrative possibilities in figurative work—hinting at memory, vulnerability, or the unspoken. Below I share practical techniques I use in painting and mixed media to weave purposeful imperfections...

studio visit: organising an artist’s routine around natural light and limited space

studio visit: organising an artist’s routine around natural light and limited space

Stepping into a small studio means learning to be resourceful. My current workspace is compact, north-facing and blessed with a large sash window that floods the room with soft, indirect light for most of the day. I’ve built my working routine around that light and the constraints of limited space — it’s shaped everything from my daily schedule to what I keep on the workbench. Over years of...

how to plan a solo show from concept to installation within a tight budget

how to plan a solo show from concept to installation within a tight budget

I’m often asked how to pull together a solo show when time is short and the budget is even shorter. Over the years I’ve learned that a focused concept, a tight timeline and a few practical shortcuts will get you from first idea to hanging flush on the wall — without losing the integrity of the work. Below I share a step-by-step approach I use when planning solo exhibitions on a shoestring:...

how to teach mark-making to beginners: three classroom exercises that spark creativity

how to teach mark-making to beginners: three classroom exercises that spark creativity

When I teach mark-making to beginners, I aim to create an atmosphere where experimentation feels safe, playful and deliberately low-stakes. Mark-making is about decision-making: line, pressure, speed, tool choice and surface. My goal is to help students move from hesitation to curiosity — to try marks without worrying about 'getting it right'. Below are three classroom exercises that I use...

review: portable led panels for plein air painters — pros, cons and battery tips

I take my painting outside as often as I can — there’s something about the day's shifting light, wind, and the odd passerby that keeps my practice alive and frank. Over the years I’ve tried a few solutions for portable light when the weather turns grey or when I want to extend a short golden hour: headlamps, clamp lights, even lanterns. Recently I started using small LED panels designed for...

five quick compositional studies to improve confidence when starting large canvases

five quick compositional studies to improve confidence when starting large canvases

When I stand in front of a primed large canvas for the first time, there’s a small, familiar flinch — part excitement, part dread. Large formats ask for decisions that feel irrevocable: scale, focal point, and how marks will breathe across the surface. Over the years I’ve developed a set of quick compositional studies that act like a warm-up for the brain and body. They help me move past...

materials checklist and process for durable mixed-media mural work on board

materials checklist and process for durable mixed-media mural work on board

I make a lot of work on board — panels feel reassuringly stable, portable and durable, and they respond beautifully to layers of paint, collage and surface manipulation. When I translate that studio approach into large-scale mixed-media mural work on board, the challenge becomes one of making each element robust: adhesive layers that don’t delaminate, paint that resists cracking, and finishes...
