Cut a Skate Shark Stencil Kit from a Photo
Turn a mako shark photo into a four-plate spray-paint stencil kit in Lopsy, with cut chipboard cards, overspray, a sprayed skate deck and grease pencil.

Multi-layer spray stencils are how a lot of skateboard graphics start. You split a picture into a few flat tones, cut one card for each tone, and spray them one after another onto the board, lightest first. Each card is called a plate. Holes in the corners line the plates up, so the colours land "in register".
In this tutorial you'll make Mako Jaws, a 2400 × 1600 px stencil kit for an invented skate crew. It's laid out like a contact sheet. Four cut chipboard cards sit on a cutting mat: a bone base, a teal mid tone, a black key and an orange lettering plate. Next to them is the sprayed deck proof, circled in grease pencil as the pick.
The shark comes from a photo: Isurus oxyrinchus by Mark Conlin, taken for NOAA's Southwest Fisheries Science Center and in the public domain. Download the full 1130 × 753 px version from its Commons page. Any side-on shark or fish photo against open water works the same way.
Along the way you'll use:
- Define Pattern and Fill with Pattern for the mat grid, the Pencil with Shift-click straight lines, Add Noise and Clouds
- pasting a photo, the Magic Wand with Shift-click seeds, an Option-drag Lasso to subtract, and Select → Inverse
- Desaturate, Gaussian Blur, Brightness/Contrast and Posterize to split the photo into tones
- Grow, Shrink and Feather, and Cmd-clicking layer thumbnails to cut one layer with another
- groups, Duplicate Layer, and scaling and rotating several layers at once with the Move tool
- ruler guides with snapping marquees
- the Pen tool, text on a path, letter spacing, Rasterize Layer and Merge Down
- the Spray tool, the Brush, Fibers, a layer mask, and the Multiply and Soft Light blend modes
- the Drop Shadow, Stroke, Inner Glow and Outer Glow effects
- copy and paste, dragging layers in the Layers panel, and undo and redo

Draw one grid tile
A cutting mat has a printed grid. You'll draw one square of it and repeat it.
- Click Layer 1 and rename it
Grid Tile. - Pick the Pencil, set Size to
2and the colour to . - In an empty area near the top left, draw a horizontal line and a vertical line that cross, each about 120 px long. Click to start a line, then hold Shift and click to finish it.
- Set Size to
1and draw a second, thinner pair 50 px further right and 50 px further down. These are the half-way lines. - Pick the Rectangular Marquee and, with nothing selected, click once (don't drag) on the point where the thick lines cross. A Rectangular Selection dialog opens. Type the crossing point into From X / Y and add 100 to each for To X / Y, so you get an exact 100 × 100 px square, and apply it.
- Choose Edit → Define Pattern, deselect with Cmd+D, and delete the
Grid Tilelayer.

- Click Layer 1 and rename it
-
Fill the mat with the grid
- Click Add Layer and name it

Select the water with the Magic Wand
- Pick the Magic Wand, set Tolerance to
40and tick Contiguous. - Click the bright water near the top left.
- Hold Shift and click the water in seven or eight more places, from the bright cyan at the top to the deep blue at the bottom and right. Each click adds to the selection.
Zoom in and look closely at the ants round the dorsal fin and the tail. They are dark navy, close to the deep blue water, so the wand can easily take part of them too.

- Pick the Magic Wand, set Tolerance to

Take the fins back with the Lasso
If the ants cut across the base of the dorsal fin or the tail, take them back:
- Pick the Lasso.
- Hold Option and drag a tight loop around the dorsal fin. Option-drag subtracts from the selection.
- Do the same around the tail.

-
Delete the water and the specks
- Press Delete to clear the water, then deselect.
- Bubbles and specks are left floating in the water. Lasso a loose outline around the whole shark, choose Select → Inverse, and press Delete again.
- Deselect and rename the layer

Redraw the tail as a crescent
The photo cuts off the bottom of the tail. Cut as it is, that would make a straight bar on the stencil instead of a fin.
- With the Lasso, loop around the tail from the narrow point where it joins the body, and press Delete.
- Draw the new tail as a lasso shape. Start at the narrow stalk, sweep out to a pointed tip above the body line, curve back in to a notch in the middle, then out to a matching tip below and back to the stalk. A mako's tail is almost symmetrical, like a crescent moon.
- Fill it with , a mid blue that will posterize into the dark plates, and deselect.

Group and duplicate the plates
First add guides for the card layout: two 740 × 600 px card spaces across and two down, with gutters between them, leaving a column on the left for the deck. Click the top ruler at
770,1510,1600and2340, and the left ruler at250,850,930and1530. Each click drops a guide.You need the plates twice: once to cut the cards and once for the sprayed deck.

Deal one plate onto each card space
The guides mark four card spaces: two across and two down, to the right of a column left free for the deck.
- Click
Plate Baseand drag it with the Move tool into the middle of the top-left space, a little below centre to leave room for a label. - Drag
Plate Midinto the top-right space andPlate Keyinto the bottom-left space.
The plates have to stay in register, so move each one by exactly the same amount relative to its space. The spaces are 830 px apart across and 680 px down. Hover the shark's nose tip on
Plate Baseand note its X and Y in the status bar. The same point onPlate Midshould end up 830 px further right, and onPlate Key680 px further down. Drag close, then switch to the Move tool's arrow keys for the last few pixels (Shift moves 10 px).

Smooth the plate edges
Real stencils are cut with a knife, so the wand's ragged edges have to go.
- Zoom in on each plate. Box any tiny floating speck with the Rectangular Marquee and press Delete. Delete the eye and the little gill slits on the key plate too, because they're too small to cut.
- On each plate, Cmd-click its own thumbnail, run Shrink
4then Grow4, choose Select → Inverse and press Delete. This trims the thin, ragged bits. - Cmd-click the thumbnail again and run Grow
4then Shrink4. Set the foreground to that plate's colour (bone, teal or black) and fill. This fills in the little nicks.

Click the previous card's row before adding each new card layer.Before you finish each card, zoom in and look for islands: pieces of card that the cut has separated from the rest. In a real stencil they would fall out. Stencil cutters leave thin straps called bridges to hold them.
- Pick the Pencil, set Size
