looking for round ss thimbles

[seawolf]

Hello all,
I am gathering supplies for my life line project, utilizing the Endura 12 or Amsteel Blue.
Haven't decided, but leaning torward the blue as its dark blue color will match the hull color better.
My question:
I am having a hard time finding Round SS Thimbles on line. I have found source for brass ones. Where can I find these thimbles in stainless?
I wanted to splice these in where I will be lashing the lines to the deck fitting and at the stern pulpit.
I will be using 1/4" or 5/16" line. What would be the suggested size of thimble for proper amount of lashings and still be slick looking?
Thanks as usual for any assistance.
Bob
