Tartan

If it's the perfect colour, I use it. I am not afraid of the Quilt Police!

I try to use the same on the top and bottom - but I do not know if it really matters or not
.
I also use whatever - but because a lot of the thtead I have is 'older" - I do check it for strength before using it.

the poly thread will not melt now days

poly is fine, people use it all the time. I just used so fine poly to piece a quilt, worked just fine.

What kind of thread I use depends on what I'm doing. The one I'm working on right now had a lot of piecing and quilting.

So I decided to use Maxilock serger thread so I don't go broke just buying thread. If it's on sale I can get two 3K cones for $5. I believe it's cotton. I can iron it at any rate.

What I'm working on now has cream backing so for decorative topstitch I'm using tan Coats & Clarks with white serger thread in the bobbin.

Of course the thread doesn't fit on my Singer 9022. I hung the cone upside down from the chandalier with a rubber band paper clip binder clip affair. It's cheap, it works so I'm happy.

Using a fine cotton thread in both top and bobbin (Aurifil 50wt 2-ply) works best for me. I have tried experimenting using polyester thread for piecing. When using in both top and bobbin, I find that the stitches at the end of a piece are much more likely to loosen. On my machine, if I use poly in the bobbin and cotton on top, I notice that my seams do not lie as smooth. It probably depends on how picky you are and perhaps also on how your machine handles these threads.

Mettler thread is not 'wrapped' in silk. The 'silk' - which is actually 'silk finish' refers to the manufacturing process and is 100% cotton. A common misconception.

I agree - I use Superior's Bottom Line (60 wt poly) for everything and it never, ever melts either. And I use a hot iron.

I made a beautiful quilt. I sandwiched it and was quilting it and it all was coming apart. When I checked the seams, the thread was really stiff and scratchy. I continued quilting by stitching very very close to the seam on the side the seams were pressed. what happened was when I ironed the top getting it ready, I melted the thread. It held until I was quilting and it was too late to re stitch the seams. did the best I could.

lesson learned, never again.

I have tested both my YLI nylon monofilament thread and my poly thread by placing a strand on my ironing board and ironing with my hottest iron setting (which on my Rowenta is very hot!). Neither melted. In fact, I could not perceive any change in the threads even after leaving my hot iron on them for a minute at a time. I think a problem with melting thread is a rarity these days. Manufacturing advances are probably the reason.
