2. Zizit made of linen (flax) or sheeps' wool may be used on any type of clothing with the exception that linen zizit may not be placed on wool clothes, and wool zizit on linen clothes in our times when we do not possess techelet, since wool and linen are kela'im (forbidden to be worn when attached together). (Sh.Ar.9)

As quoted from:
Shulchan HaMelech, a Kitzur Shulchan Aruch in 3 volumes as compiled by Maharan HaRav Shmuel Laniado z'al, 1923 with the supplement "Al HaShulchan" containing various opinions compiled by Ezra Basri, Chief Justice of the District Court, Jerusalem in 1992.
We would like to dedicate this learning for the speedy and complete recovery of two people: our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia, and a longtime friend of the family, Frank, son of Joseph, having thyroid surgery soon. Please have them in mind when studying. If you would like updates on their progress, please let me know so I can tell you when I find out from either or both.
