Now if I remember correctly, SewOK a few posts back mentioned her Mexican Gutermann thread fraying and breaking needles. The Gutermann representative told me their thread from Mexico is upholstery thread. Therefore, if SewOK is being used for quilting perhaps, that would make a difference--definitely the type of needle used would be important with upholstery thread.quote]
OK, I've got my boxes of C&C threads, and Gutermann here by my side. I'm looking at C&C first because we had discussed it some place way back there. C&C tells you what kind of use the thread is for. Mine are mostly All-Purpose 100% Cotton. But others are for special purposes such as carpet/ button, hand quilting, and all that good stuff.
Gutermann's spools say, Gutermann, Germany, 100% polyester, and the amount of thread on the spool. There are some numbers on the top of the spool, but they would mean little to most of us, I'm sure. They mean nothing to me. I also have some Mettler which say, Mettler silk finish 100% cotton merc., Spain made, No. 50. Plus a bunch of numbers also.
I also have some large spools that I picked up in Italy while on a visit there. This thread is what the Italian women swear by, supposedly. They say ... No. 50, Pure cotton mercerized, 1000 yards, RADIX which is the company.
The only thread spools that actually say WHAT the thread is especially made for are Coats & Clark's. Score one for C&C!
We have all probably been using the wrong types of threads for our piecing, not always, but certainly some of the time.
Yet another bit of detective work from a member of the Sherlock Holmes Society quilting board! 8-)
