as long as the thread is strong (doesn't break when you tug on a length) it is fine to use.
for cones with your domestic machine you probably need some sort of holder for the thread cone- there are a few on the market from quite simple-fairly inexpensive- to fancy- quite expensive.
i use a box- that a tall travel cup came in- i just drop the cone in the box- set it beside/behind the machine bring the thread up & thread as usual- works well for me-
i've heard of people using tins, bowls, what ever will work to hold the cone upright so the thread feeds off the cone the way it should.
