Bismarck 1/350 - How to mask the swastika circles?

Evening all.

I need to mask the white disks over which I can place the swastikas on the decks of my 1/350 Bismarck. Any ideas how best to do this (or pre-cut masks I can buy)? I guess I could scribe a circle using dividers and try and cut it out but not sure how neat I could make that.

What do you think?

Wish I can help… I am into armor only but I would post this question in ships forum to get an answer. One day I will build Bismarck when I am ever tired of building armors. [:D]

Thanks. I don’t know why I didn’t do that straight away! [:$]

Glad it worked… I saw few responses already! Good luckl with your Bismarck…
