I felt like I had to make this xD If you have Photoshop, please skip Step 1 and Step 2, I have both, but I use GIMP b/c it is easy to use. Also, you cannot have GIMP w/o having GTK, and don't worry, they barely take up any space put together. Also, for Step 4, you must sign up on the website to get full-size renders, also if you don't sign up, it will have a gross black background, and for best quality, and should have no background at all.
Step 1. Download GIMP
Step 2. Download GTK
Step 3. Open GIMP or Photoshop
Step 4. Go to PlanetRenders and get the object/person that is going to be in your spray.
Step 5. Once GIMP or PS is open, click File --> New, then make it 256 by 256 px.
Step 6. Mess around with it for a while, then it should look something like this.
Step 7. Save it as a .PNG (GIMP ONLY: Make sure you click on Merge All Visible layers after you save it, a box should come up asking you for MAVL or Flatten Image.)
Step 8. Download VTFEdit
Step 9. Launch VTFEdit
Step 10. Upload your spray, then save it as a VTF. NOTE: Save it in C:\Program Files\Steam\steamapps\YourUsername\team fortress 2\tf\materials\VGUI\logos
Step 11. Launch Team Fortress 2. Then go to Options --> Multiplayer --> Import Spray. Then Find Your Spray, and Open It.
Step 12. Enter a server, go up to a wall, and hit "T"!
Q: Where did you get those blood patterns?
A: Search "GIMP Brushes" at www.deviantart.com Once you find one you like, download it, and save it to the GIMP/brushes folder.
Q: Where do you get fonts?
A: Just search up fonts on google, once you find one you like, save it in your WINDOWS/font folder.
Q: What is a render?
A: Simply a picture of one thing, that has a transparent background.
Q: Why does your spray look kind of bad?
A: 'Cause it was just for a tutorial, and I didn't feel the need to make it look fancy.
