:? This is a free-motion quilting question. Why does my bobbin thread color show through on the top sometimes when I am free-motion quilting and using a different color on the top and bottom. It doesn't always show.. Is it a quirk of my machine? I have a Pfaff Tiptronic 2030. :?:

I don't know that particular machine, but I would check the tension settings. Also, check that your needle is the right size.

It's probably your tension. It does it to me too.

that used to happen to me on the curves of FMQ. I speed up on the curves now. If I go slow it shows.

It is the tension, I just set mine a bit higher until it stopped. And it will still do it when making a turn as babeegirl said so just adjust how fast you go until you get it right. Good luck! I'm just learning also and I think the main thing is PPP.

I do a lot of FHG, I only do small wall hanging and nothing larger then a twin sized quilt. I no longer use a long arm as it bothered my bad so bad. I use a Janomi 6500 that has a little larger bed. There's another issue besides tension. You should to use the same weight thread in the bobbin that you use on the top! Weight of the tread can have a lot to do with this too. If you use clear try to use Polyester and not nylon, with that use a needle with a larger eye and in this case you'd loosen the tension top and bottom. Bobbin thread tension should be a real low number. More information then you asked for but if you use metallic threads or the clear use a Schmetz Metallic Needle 90/40.
I'll post one of my table runners in the pictures...


Hope this helps,
