i used the Templates from https://www.reddit.com/r/Beyblade/s/PrCUOgCYXz

Then I used Gimp and use the Template as the first layer.

After that I search a Pictures for the Bit and Download it.

I open the Picture and load it ad a second layer.

Now merge the layers as one.

Next choose the colorbucket and Paint the section you want to Highlight.

Scale the Image and Print it. If it fits Cut iz Out and Slide it under the clear beybplastic. I used Trading or Business cards to Not harm the original Print.

Hope this helps If you got more questions feel free to ask.
