Dyeing to be Holy
There has been much debate about the blue dye (techelet) for one string in the tzitzit. Here is an interesting article for thosewho may want to learn more.
I am able to supply these tzitzit (at an additional cost of $25) but the synthetic type is recommended so that the dye does not rub off on your clothing!
If the blue string is simply symbolic, I can dye the shamash string to a shade of blue very close to authentic.
