[Solved] Making stickers from scratch

[Paweł Turalski]

You should use a 1-4chrd.dat NOT a 1-4disc.dat.

Ah yes, my mistake! But does it change anything?
Also thank you for this link, it was really helpful, I used the inverted 1-4ndis in one corner, because it is in two colours. That was fun to experiment with different primitive 
   

But the 1-4disc works too, and feels easier to control. Of course if it technically changes something, I can use 1-4chrd instead
   

Now I have another question - how to make the pattern smaller? When you look at the exported preview, it sticks to the edges. The sticker is always smaller than the part, so in this case it should be smaller too. I cropped the sticker from full sticker sheet and used it as background image. I cropped it o the edges of the real sticker you apply, without that margins that are left on the sheet. So the pattern is made correctly, but needs to be scaled. How?
