Just curious but are you wanting to use two threads to make the quilting more "in your face" or are you doing it to combine colors? If "in your face" why not try Wonderfil's spaghetti thread? It is a 12 wt you can run through the top on your longarm. Well supposedly. That is what the wonderfil people told me and they had samples there that Kim Stotseneurg had done (she quilts on an A1). It definitely gives dimension and pow factor to quilting and it stood out fabulously and they have some great colors to choose from. I have yet to try it myself but I bought several spools with the intent to try. I am thinking this may be a good alternative to double thread for you and your robotics. Especially if your design has backtracking involved.

Another option to consider with heavy decorative threads, is load it in your bobbin and load your sandwich upside down. I have another friend who does amazing bobbin work on her Innova and uses all the pretty fancy threads like Razzle Dazzle and Candlelight.

Peckish, yes I've been meaning to try metallic with another color thread in the needle too. Since metallic is fragile as we all know I would probably only use it for wall hangings or something that won't be washed too often. I did use it a little on a baby's quilt though. Have no idea how its holding us as it went to a grandchild of my sister's down in TX.

FanaticFeline, I'm not going for "in your face" effect but just wanting to use it for the 2-color effect. Its for my dining chairs so lets face it, no one will see it most times as the chairs are pulled into the table and when they do pull the chair out, they'll be planting their tushes on it so again won't see it. Its basically for me to try this technique out mostly.

Also have another question on the threading of the 2 threads on a quilting machine. Would I thread them both the same way or does one need to be on the outside of the tension disks? Just something someone mentioned but that may be for a regular sewing machine more so than a quilting machine.

Thanks gang for all your insight on this technique.

If you like cotton, king tut by superior doesn't shred and break. I had breakage with all other brands with the exception being presencia since I have not tried that brand I can't comment

Hi lady's
This post intrigued me. I like to try new thing. This is why I read most all the post on the board. I sure learn a lot.
I have sewn with twin needles. I have also sewn by putting both thread (2) threads thru the same needle eye Like someone said "separate thread spools but treated the threads "as one" .
I also read something about using a single needle with two holes in it. One is on top of the other. I have never heard of this kind of needle . I sew on a Domestic vintage Kenmore 15813450. The needle that this machine use is a "normal" needle you can buy at any "fabric store". Does anyone know if I can use one of this needles on my machine and where to buy them?
Also where do you buy Wonderfil's spaghetti thread? I checked at my JoAnn's with no luck on the thread.
Thank you so much. I enjoyed this post.
