I have almost finished up Tamiyas 1/35 tank crew at rest kit, I still need to hit them with a matte varnish.

Overall I am pleased with how they turned out as these bring my total built figures to just 10. One thing I found frustrating was trying to paint the piping on the uniforms. I saw this part as a complete disaster on my end as you can tell by the photo. Is there a tried and true technique to get better results on such thin lines?
