Step 1: Sketching Our Sticker
Since we're going to make our own stickers pack, I decided to create a drawing of my invention to avoid infringe copyright. When drawing, try to close all the strokes, and remark the outline since this is going to work as a basis to create our image vector with illustrator. I created a not very elaborate drawing to make it easier.
Step 2: Scan/take a Picture of Your Sketch
Then, we need to scan or take a photo with a HQ camera to create a digital version of our sketch and open it in illustrator. What I'm going to do is to create a new file in illustrator and then put our sketch in a new layer. I'm using a 512 px canvas because that is the size required by telegram for the stickers.
Step 3: Outline the Main Parts of Our Sketch
This is so easy, I'm only going to use the ellipse tool to create the face of my drawing and then the pencil tool for the other parts. I'm using a different layer for each of the shapes.
Step 4: Color Your Shapes
You only need to set the shapes you created with the color fill you like the most and remove the stroke.
Step 5: Placing the Bubble Message
Step 6: Saving Your Image As Png
It's important to save our picture as png, since we don't want any background.
Step 7: Create a New Stickers Pack in Telegram
We are about to finish, we only need to go to telegram and search @stickers and start a new conversation with the "stickers bot". It will answer automatically and you need to follow the directions. Actually if you consider your stickers are a great art work you can sell them to telegram for 100 USD.
Step 8: Have a Lot of Fun Using Them! :)
Send it to your friends, create viral stickers! :D
