How to Make White Border for Stickers Procreate
StyleFrame Team6 min read
To make a white sticker border in Procreate, duplicate your artwork layer and fill the copy with white using Alpha Lock. Blur the copy with Gaussian Blur, then use Automatic Selection, Invert, and Fill Layer to put a solid white shape on a new layer beneath the art. Procreate has no offset-path command, so the blur-and-select trick stands in for one. Smoothing the edge with a monoline brush gives you a cleaner border for printing or cutting.
What You Need Before You Start
The method is built for art that sits on a transparent background, so a few setup choices save time later.
- Put the sticker on one layer. If your design is spread across several layers, merge them. For a full sticker sheet, merge everything into one layer so you can generate every border in a single pass. Work on a duplicate of the project so the originals stay editable.
- Hide the background layer. A white border is invisible against a white canvas. Switch the background off, or temporarily set it to a dark color, so you can judge the border as you work.
- Check your canvas resolution. The border is built from blur and selection, so a low-resolution canvas gives you a coarse edge. If the sticker is headed to print, work at the final print size.
Step-by-Step: The Blur-and-Select Method
This is a popular approach. It works well with some artwork and less well with others.
1. Duplicate the artwork layer
Swipe left on the layer and tap Duplicate. You now have two identical layers. The bottom one becomes the border source, and the top one stays as your untouched artwork.
2. Fill the bottom copy with white
Select the bottom copy, tap the layer, and choose Alpha Lock. Set your color to white, tap the layer again, and choose Fill Layer. Because Alpha Lock is on, only the painted pixels turn white and the transparent area stays empty. You get a flat white silhouette of your design.
An alternative is Adjustments, then Hue, Saturation, Brightness, with brightness at 100% and saturation at 0%. It gives the same white silhouette without Alpha Lock. Use whichever you find faster.
3. Turn off Alpha Lock and blur
Switch Alpha Lock off, then open Adjustments and choose Gaussian Blur. Drag your pencil across the canvas to increase the blur. The white silhouette softens and spreads outward, swallowing small gaps and details.
Values around 10 to 25% are a common range, but the right number depends on canvas size and how thick you want the border. Keep going until the blur fully covers the design's edge, including any thin strokes, small islands, and lettering counters.
4. Select the blurred shape
Open the Selection tool and make sure Automatic mode is on. Tap on the empty canvas outside the blurred shape, then drag your pencil to adjust the selection threshold.
- Dragging right increases the thickness of the border.
- Dragging left gives a finer, thinner border.
Everything except the border area should now be highlighted. Tap Invert so the selection becomes the blurred white shape instead.
5. Fill the selection on its own layer
Create a new layer beneath your artwork. With the selection still active, tap the layer thumbnail and choose Fill Layer. You now have a clean white shape behind the sticker. Delete the blurred helper layer, or hide it if you want to re-run the process with different settings.
A shortcut some artists use: if Color Fill is set to white when you invert, the selection fills automatically, so you can skip the manual fill step.
Fixing Common Problems
The method is fast but not perfect. These are the issues you will most likely hit.
Bumpy or wobbly edges
Because the border follows a blurred edge, it can pick up small irregularities. That matters little for screen use but a lot for cutting machines. Pick a smooth monoline brush in the same color as the border and trace around the edge on the border layer. You can also run the quick method for the base shape, then clean up only the areas that look rough.
Holes or gaps inside the border
If you see pinholes or empty pockets, the blur was not strong enough to bridge them. Undo the selection, increase the Gaussian Blur, and redo it. For small leftovers, fill them by hand with a brush on the border layer.
Border is too thin or too thick
The selection threshold controls thickness, not the blur amount alone. Redo the selection and drag further to widen or narrow the result. If the blur is too weak to reach across the whole design, increase it first and then fine-tune the threshold.
Soft or semi-transparent edges
Brushes with low hardness or opacity produce faint edge pixels, and the selection reads those inconsistently. If a sticker has a lot of soft shading at the edge, the border can look uneven. A hard-edged brush on the outermost strokes gives the selection more to grab.
Border Variations Worth Knowing
Once the base shape exists, small changes give you different looks.
- Colored borders. Use a different fill color in the Alpha Lock step and every later step follows. Cream, black, or a brand color all work.
- Drop shadow. Duplicate the border layer, drag it to the bottom, invert its colors to make it black, add Gaussian Blur, and lower the opacity. Nudge it slightly down for a lifted-off-the-page feel.
- Double borders. Run the process twice. Use the first border as the source for a second, larger outline in a different color for a layered die-cut look.
- Lettering and text. The same approach gives hand-lettered words and fonts a sticker-style backing. Rasterize text first.
Preparing the File for Export
Think about the destination before you export.
- For print-and-cut: Export the sticker with the border as a PNG on a transparent background. Keep the border on a separate layer so you can reuse it as a cut line. Smooth the edge first, since cutters follow every bump.
- For digital use: Export a PNG with transparency at a size suited to the platform. Include the shadow only if the background will be light enough for it to read.
- For motion work: Export the artwork and border as separate transparent PNGs, or as a layered file, so you can animate them independently.
Taking Procreate Stickers Into Motion Work
Many sticker designs end up on screen as animated overlays, social elements, lower thirds, or title-card decoration. In that case Procreate is only the first stage. Bring the transparent PNGs into your compositing app and you have a few options.
- Keep the Procreate border as its own layer. This lets you animate the border and artwork separately, such as a peel-off, a wobble, or a slight offset between layers.
- Add the shadow in compositing. A shadow added in your compositing app is easier to adjust over time than a baked-in shadow from Procreate.
Quick Checklist
- Merge the sticker art onto one layer and hide the background.
- Duplicate the layer and fill the bottom copy with white using Alpha Lock.
- Turn off Alpha Lock and apply Gaussian Blur until the shape is fully covered.
- Use Automatic Selection, adjust the threshold, and tap Invert.
- Fill the selection on a new layer beneath the artwork.
- Smooth the edge with a monoline brush if you plan to cut or print.
- Export as a transparent PNG, and keep the border on its own layer if you plan to animate.
Once you have done it a few times, the process goes quickly. It saves you from hand-tracing every border.
