How to Create a Cartoon Bomb Icon with Sketch App

It's the bomb!

This tutorial will teach you the essential techniques required for creating custom icons with Sketch. And in the process you will create a cool, cartoon-style bomb icon.

Step 1

icon design tutorial for sketch app Launch Sketch and begin by drawing a green rectangle to use as a background layer. Then right click on the layer in the sidebar and select Lock Layer to avoid accidentally selecting it again. Rectangle:
  • Fill: #95A782
  • Border: None
  • Position: X:0 Y:0
  • Size: W:900 H:600

Step 2

icon design tutorial for sketch app Next draw a purple circle near the center of the background layer, using the Oval tool and holding down the shift key to constrain proportions. Circle:
  • Fill: #816F85
  • Border: None
  • Position: X:168 Y:168
  • Size: W:900 H:600

Step 3

icon design tutorial for sketch app Place a small rounded rectangle near the top of the circle, aligned to the center of the circle horizontally. Rectangle:
  • Fill: #816F85
  • Border: None
  • Radius: 6
  • Position: X:421 Y:204
  • Size: W:38 H:30

Step 4

icon design tutorial for sketch app Select the Rotate tool and move the anchor point for the small rectangle to the center of the circle, then rotate the rectangle 45° clockwise. Rectangle:
  • Transform: 315°

Step 5

icon design tutorial for sketch app Select the circle and rectangle layers and combine them with the Union boolean function

Step 6

icon design tutorial for sketch app Now add some styles to the merged bomb shape: Bomb:
  • Fill: #816F85
  • Border: #434343, Outside, 6
  • Inner Shadows: Black, Alpha:20, X:-12 Y:-12, Blur:0, Spread:0

Step 7

icon design tutorial for sketch app Use the Pen tool to draw a short wavy line from the center of rotated rectangle, to approximately half down the circle. Use 3 points in total including the start and end points then remove the fill and add a border: Fuse:
  • Fill: None
  • Border: #EBCFA8, Center, 8

Step 8

icon design tutorial for sketch app Go to the Layer > Paths menu and select Vectorize Stroke to convert the border to a fill so that we can add additional styles to the fuse: Fuse:
  • Fill: #EBCFA8
  • Border: #434343, Outside, 6
  • Inner Shadows: Black, Alpha:20, X:-4 Y:-4, Blur:0, Spread:0

Step 9

icon design tutorial for sketch app Add a new pattern fill layer above the solid color fill and select the diagonal lines default pattern (or use your own if you have a better one). Fuse:
  • Fill 1: Diagonal lines pattern
  • Fill 2: #EBCFA8

Step 10

icon design tutorial for sketch app Use the Star tool to draw a new shape slightly overlapping the fuse and bomb shapes. Star:
  • Fill: #FFFFFF
  • Radius: 68%
  • Points: 8

Step 11

icon design tutorial for sketch app Add 3 borders to the star layer to create a spark effect. Reorganize if necessary to get them in the following order from top to bottom: Star:
  • Border 1: #434343, Outside, 6
  • Border 2: #F2780D, Inside, 6
  • Border 3: #F5A623, Inside, 12

Step 12

icon design tutorial for sketch app The bomb is currently looking a little bit flat, so let's add some extra lighting. Draw a new circle layer with no fill and a white border, in the center of the round part of the bomb. Circle:
  • Fill: None
  • Border: #FFFFFF Center 6
  • Position: X:372 Y:241
  • Size: W:134 H:134

Step 13

icon design tutorial for sketch app Double click the circle layer to enter the path edit mode, and then click the Open Path button to open up the circle.

Step 14

icon design tutorial for sketch app Delete two of the vector points so that only the top left quarter of the circle remains.

Step 15

icon design tutorial for sketch appCircle: Select the Border options and add a dashed stroke, and lower the opacity of the layer to 20%
  • Fill: None
  • Border: #FFFFFF Center 6
  • Dashed Options: Ends: Round, Dash 80 Gap 15
  • Opacity: 20%

Step 16

icon design tutorial for sketch app Draw a small white star near the top of the bomb shape. Star:
  • Fill: #FFFFFF
  • Border: None
  • Points: 5
  • Radius: 50%
  • Position: X:450 Y:205
  • Size: W:32 H:32

Step 17

icon design tutorial for sketch app Double click the star shape to enter the path edit mode, select all of the points on the star and set the corner radius to '3' to soften the shape. Star:
  • Corners: 3

Step 18

icon design tutorial for sketch app Rotate the star 30° clockwise around the default anchor point. Star:
  • Rotate: 330°

Step 19

icon design tutorial for sketch app Duplicate the star, then move it to left, reduce the size slightly and rotate -45° anti-clockwise. Star:
  • Rotate: -15°
  • Position: X:489.7 Y:218.6
  • Size: W:18.1 H:17.3

Step 20

icon design tutorial for sketch app To create a shadow, draw a new Oval shape layer below all other layers except for the background: Shadow:
  • Fill: Black, Opacity 20%
  • Border: None
  • Position: X:388 Y:385
  • Size: W:104 H:21

Step 21

icon design tutorial for sketch app The bomb actually looks pretty cool at this stage. But to finish it off, let's draw a friendly skull and crossbones sign onto the bomb to signify danger. Start with a simple circle for the skull head: Circle:
  • Fill: #ECD6C3
  • Border: None
  • Position: X:421 Y:278
  • Size: W:40 H:40

Step 22

icon design tutorial for sketch app Use a small rounded rectangle for the jaw section of the skull: Rectangle:
  • Fill: #ECD6C3
  • Border: None
  • Radius: 6
  • Position: X:429 Y:308
  • Size: W:24 H:14

Step 23

icon design tutorial for sketch app Next up, lets give our skull some eyes. Draw two circles (or just one and duplicate it for the second). The only difference will be the X position values. Eye 1:
  • Fill: #816F85
  • Border: None
  • Radius: 6
  • Position: X:429 Y:298
  • Size: W:10 H:10
Eye 2:
  • Fill: #816F85
  • Border: None
  • Radius: 6
  • Position: X:443 Y:298
  • Size: W:10 H:10

Step 24

icon design tutorial for sketch app For the nose, use the triangle shape tool to draw the basic shape. Then double click the triangle to enter the path edit mode, select all 3 vector points and set the Corners value to 2. Nose:
  • Fill: #816F85
  • Border: None
  • Corners: 2
  • Position: X:438 Y:307
  • Size: W:6 H:8

Step 25

icon design tutorial for sketch app Next up are the crossbones. Start by drawing a basic rectangle: Rectangle:
  • Fill: #ECD6C3
  • Border: None
  • Position: X:412 Y:329
  • Size: W:60 H:6

Step 26

icon design tutorial for sketch app Draw a small circle intersecting with the top left point of the rectangle: Circle:
  • Fill: #ECD6C3
  • Border: None
  • Position: X:407 Y:324
  • Size: W:8 H:8

Step 27

icon design tutorial for sketch app Duplicate the circle layer 3 times, one for each of the rectangles other corners. Then select all 4 circles and the rectangle and combine them with the Union function. Circle 1:
  • Position: X:407 Y:324
Circle 2:
  • Position: X:407 Y:331
Circle 3:
  • Position: X:467 Y:324
Circle 4:
  • Position: X:407 Y:331

Step 28

icon design tutorial for sketch app Take the combined bone shape and rotate it 15° clockwise. Bone:
  • Rotate: 345°

Step 29

icon design tutorial for sketch app Duplicate the bone shape and flip it horizontally.

Step 30

This is how the bomb should now look: icon design tutorial for sketch app We could happily call this finished now, but I do have one last optional final touch..

Optional: Add speckle textures

This optional extra step involves downloading our premium Vector Speckle Textures resource. Once you have done this, place 2 of your favourite textures from the pack on layers above all of the other artwork: icon design tutorial for sketch appicon design tutorial for sketch appTexture 1:
  • Fill: White
  • Opacity: 20%
Texture 2:
  • Fill: Black
  • Opacity: 10%

Result & Conclusion

Here is the final result, I think you will agree that it looks the bomb! (sorry) icon design tutorial for sketch app This tutorial has covered a lot of techniques essential for designing custom icons, such as combining simple shapes to create more complex layers and also using layer styles to create visual effects. These techniques are also universally applicable, not just within Sketch.
