Thread ???
I bought three spools of thread this weekend. It is Gutermann Bulky Nylon and it came on a small cone shaped spool. I just got it opened and think it may be serger thread. It is beautiful on the spool, but expands and becomes really fine when it unrolls. Is it ok to use this in my regular machine? I have a new Pfaff Ambition Essential and I don't want to ruin it! Thanks!!
