homemade yellow letter issues

[Daniel Pitcher]

I'm having some trouble putting together a perfect letter.   I'm using yellow paper and printing lines on it from a template.  I have a handwritten font of my handwriting that i print back on the paper.  It would look great but theres always a line or two that get printed on the lines making the letter look fake.  

Does anyone have any experience in tweaking the spacing?  I've spent a fair amount of time trying to wiggle it around.  There must be a better way.

Thanks for reading!
