Want your curtain visualizations to look real, not flat? A textile decorator with 19 years of experience explains exactly which Procreate blend modes actually matter — and which ones to skip.
By Sviatlana Fedzianiova, textile decorator with 19 years of experience and founder of an online school teaching Procreate visualization for curtain and textile professionals on iPad and iPhone.
I'll be honest — when I started doing curtain visualizations in Procreate, everything looked flat. Like a coloring book. Clients would nod politely but you could see they weren't impressed.
Then I figured out blend modes. Now my renderings look like photographs, and clients stop scrolling to ask: "Wait, is that real or did you draw that?"
Here's what actually works — and what's a waste of time.
Multiply — For When Your Curtains Look Like Cardboard
This is the one I use most. It adds shadows.
Without shadows, your curtains have no depth. They look like they're floating. With shadows, suddenly there are folds, pleats, and dimension.
Here's what I do: new layer above the curtain, set it to Multiply, grab a soft brush and turn opacity down to about 30%, paint gray where shadows should be.
Where do shadows go? Anywhere fabric overlaps. Under pleats. Behind folds. Where the curtain meets the wall.
Takes maybe five minutes. Makes a huge difference.
One thing I learned the hard way — don't use pure black. Use a dark version of your fabric colour. Dark blue for blue curtains, dark burgundy for red ones. Looks way more natural.
Screen — Making Light Actually Look Like Light
This one confused me at first because it seemed to just wash everything out. But once you get it, it's perfect for sunlight.
Screen mode lightens whatever's underneath it. So when you paint with a light colour on a Screen layer, it looks like actual light hitting the fabric.
I use it for sunlight coming through a window, the edges of folds that catch light, and that rim light effect you see in expensive photos.
My process: layer above the curtain set to Screen, use a warm off-white or pale yellow, paint where light would hit, usually keep it subtle around 25–30% opacity.
The mistake I made early on was painting the whole curtain. Don't do that. Light hits specific spots — edges, tops of folds, areas near windows. Be selective.
Overlay — The Fast Way to Show Different Fabrics
This one is a lifesaver when clients want to see how different patterns look during a curtain consultation.
Let's say you drew curtains and the client asks "can I see it in that damask fabric?" Instead of redrawing everything, you just drop the fabric pattern on an Overlay layer. The pattern shows up but all your shading and folds stay intact.
I keep a folder of fabric photos and patterns. When someone wants to see options, I swap Overlay layers. Five different fabric options in two minutes. Client thinks I'm incredibly fast.
The trick: lower the opacity to around 40–50%. Full strength usually looks too intense.
Darken — For Line Art Over Colour
I don't use this one as much, but it's handy for one specific thing.
If you have black and white sketches or line art — decorative trim, tassels, details — Darken mode makes the white disappear and keeps the black lines. Instead of spending forever erasing white backgrounds, just set the layer to Darken. Done.
Add — Use Sparingly or It Looks Radioactive
Add mode makes things glow. And I mean glow.
It's great for sunset through sheer curtains or dramatic backlighting, but you have to be careful. Full strength looks ridiculous — like someone installed neon lights in the curtains.
I use it at maybe 10–15% opacity maximum. Just enough to add warmth and atmosphere.
Works really well for golden hour shots — orange-pink glow through white sheers. Those renders always get the most engagement on Instagram.
Multiply for Shadows on Walls and Furniture
This deserves its own section because it's what makes curtains look like they actually exist in a room.
Real curtains cast shadows — on the wall behind them, on the floor, on nearby furniture. Without those shadows, your beautiful curtain drawing looks pasted on.
I create a layer under the curtain, set it to Multiply, and paint soft shadows where they'd fall. Soft brush. Low opacity around 20%. Gray colour. Paint where the curtain blocks light.
This single step makes everything look significantly more real. Clients stop questioning whether your interior textile visualization is accurate.

What Actually Matters
You could learn 20 blend modes. I'm telling you I use basically three: Multiply, Screen, and Overlay.
Multiply for shadows — use it a lot. Screen for highlights — use it less, be subtle. Overlay when you need to show pattern options — huge time saver.
The real workflow: draw the curtain shape → Multiply layer for shadows → Screen layer for light → done. That's 80% of what makes something look professional.
The fancy stuff — multiple shadow layers, rim lighting, atmospheric effects — that's extra. Start with the basics.
Frequently Asked Questions
What blend modes are most useful for curtain visualization in Procreate?
Three blend modes do most of the work. Multiply for shadows — paint dark versions of your fabric colour in fold areas at 25-30% opacity. Screen for highlights — paint warm off-white on fold edges where light hits at 20-25% opacity. Overlay for showing different fabric patterns — drop the fabric texture on an Overlay layer at 40-50% opacity and all your existing shadows stay intact. These three modes cover 80% of what makes a curtain visualization look professional.
How do I make curtain fabric look realistic using blend modes in Procreate?
Start with a Multiply layer for shadows — use a dark version of your fabric colour, never pure black, at around 30% opacity. Paint where fabric overlaps, under pleats and where curtains meet the wall. Add a Screen layer for highlights at 20% opacity on fold edges and areas near the window. The combination of these two layers transforms a flat coloured curtain shape into something that reads as real hanging fabric with dimension and depth.
What is the difference between Multiply and Overlay blend modes for fabric visualization?
Multiply darkens — it adds shadows and depth to your curtain visualization. Use it consistently for fold shadows and areas where fabric blocks light. Overlay shows pattern — it lets you place a fabric texture on top of an existing curtain shape without losing the shadows and folds underneath. Use Overlay when a client wants to see how a different pattern looks in the same visualization. Each serves a completely different purpose in the workflow.
Can I use blend modes in Procreate on iPhone for on-site client consultations?
Yes — blend modes work identically on iPhone and iPad. During a site visit I create the rough visualization on iPhone using the same Multiply and Screen workflow. The result is convincing enough for the client to make a decision in the room. Back at the studio I refine on iPad with more precise shadow work. The blend mode functionality is the same on both devices — only the screen size changes.
How do I avoid making curtain visualizations look too dark or too flat in Procreate?
Two common mistakes cause this. Too dark: using pure black for shadows instead of a dark version of the actual fabric colour. Pure black looks harsh and unnatural — fabric shadows have colour in them. Too flat: skipping the Screen highlight layer entirely. Without highlights on fold edges the curtain reads as a flat shape rather than three-dimensional fabric. Start both layers at very low opacity — 20% — and build gradually. It is much easier to add more than to undo overdone contrast.
Common Mistakes I Made (So You Don't Have To)
Don't use 100% opacity on blend modes. Start at 20–30% and build up.
Don't use pure black for shadows. It looks harsh. Use dark versions of your actual colours.
Don't paint light everywhere. Light hits specific places. Be intentional.
Don't forget to name your layers. When you have 15 layers all called "Layer 12" you'll regret it immediately.
Why This Actually Matters
Before I figured out blend modes, clients would say "that's nice" and then go quiet.
After? They approve designs faster. They trust the visualization. They're willing to pay more because the work looks professional.
The curtain brushes and PNG templates I sell work great on their own. But combine them with proper use of blend modes and you get results that look like you hired a 3D artist.
That's the difference between "she does nice drawings" and "she's a professional visualization artist."
