Hi everyone, 

I'm searching how I can include a logo, a letter or even a word on an infusion part. 
I'm making a part for my Caterham 7 and I want to have the 7 logo on top of it with the same fabric but with a 45°angle. 

I try to cut the fabric but it is not accurate.
I also try to put adhesive spray before cutting it; it's more accurate but it's not really easy and the result is not perfect.
Finally I try to do it with a dry fabric. Easy to cut but I didn't get a good result.

Do you have any advise? 

Edit : here is a result of a try with adhesive spray :
