I just looked at mine and most don't have the T, but I know I've seen it. Just researched it and cannot find a bit of information. Will try again.

(later) I can't seem to find anything on what the T means. Sorry.

(still later) I used several different wordings, and nothing. Then I just put T 12 and every site I went into mentioned SILK as part of the description.

Perhaps show us a photo of the labels/spools that have it.
More likely someone will recognize it with that.

Plus you didn't mention what brand(s) of thread you see this on.

I just found 5 spools Jim had bought me a few years back. They all say T 56 and hand quilting. I've read that if it says hand quilting on the label, that it cannot be used on the machine.

Yes, I believe that is true.

I don't know what the T stands for, sorry.

My thread all fits on one wooden thread rack. I have just a few poly spools and put them all on the left side, farthest from my machine. Machine quilting thread is all I have otherwise, as I don't have any specialty machines. I use those rubber "Peels" around each bobbin that has thread on it, and I use matching "huggers" for the spools. I stack the spool on top of the bobbin if the thread colors match.

My discipline is to not buy thread unless I have room for it on that ONE rack.

I try to keep my threads near the machine I use it the most but have found I'm using my embroidery thread on my quilt machine from time to time too. I have my on pegboards with those old-fashioned 36 x 36 towels over them till I can come up with a better plan to keep the dust off them. Had to add yet another pegboard when Connecting Threads changed the height of their threads as they no longer fit into my rolling cart. I use the commercial hooks so I can put the bobbin under the spool so they don't get lost for my quilt machine. Don't have a pic of the serger threads on the other side of the room but you get the idea.

Decorative Threads that I use in art quilts are sorted as follows: Vintage and antique cotton thread is kept together in three vintage thread boxes sorted by color. Vintage cotton wrapped poly and nylon are kept in another set of vintage thread boxes also sorted by color. Vintage and modern silk, rayon and trilobal poly and metallics have their own boxes and Various specialty threads are in a couple of other boxes sorted by material and whether they are able to go through a needle or must be used for bobbin work or handwork only (think Razzledazzle and other lumpy shiny threads).

Thread that I'm certain is strong enough for everyday using quilts is stored in another box that includes thread for piecing as well as quilting--- these are strong modern threads such as aurifil, isacord, wonderfil, and some of superior's threads. I keep a limited range of colors in these threads so they are all stored together in one tin.

If there is thread left over on the bobbin when I'm done then the bobbin gets stored with the thread spool- depending on spool type and what kind of storage box I'm using they either get put in the little bobbin cubbies in the vintage thread boxes, or attached to the spool/ cone with Hugo's amazing tape.

I believe the T stands for Trilobal. Trilobal means 3 ply.
