* The Torah uses different words for linen.
פשתן - פשתים - פשתה - שש - בד פשתן is while it is still attached to the
ground פשתה same as above (singular) פשתים is when it is a thread (plural, many strands) שש is after it’s beaten but before it's turned into thread. בד is when it is a fabric. Linen clothing can be
called בגדיבד,בגדי פשתן or
בגדי שש The Rambam (כלי המקדש 8- 13,14)
Paskens like our גמרא
wherever the Torah says שש the thread had to be made
with six threads (כפול שש). When it says משזר then the
thread had to be made with eight threads (כפול שמנה). *Shaarei
