Variegated thread problem - HELP!

[purrfect-lady]

My Nolting Fun Quilter is a workhorse. I usually use superior Sew Fine on top and Bottom Line pre-wound bobbins. Usually, my needles are size 20, as recommended by Nolting. It sews beautifully and dependably. But every time I try to use superior variegated thread, I get nothing but rats' nests on the bottom. I've done so much frogging I've dulled my new frogging tool! I've tightened the top tension a half-turn 8 to 10 times. It's better and in fact, when I stitch on my muslin borders, it does very well. But when I get into the body of the quilt, the rats come out! I've changed the needle and the size of the needle. I've rethreaded the machine and the bobbin. Does anyone out there have any ideas? Do you do anything special with variegated thread? When I've talked to the techs at Nolting in the past they've told me that I should never have to change the bobbin tension, so I haven't. and I've never had to before. But every single time I try to use variegated threads this happens and I'm ready to throw something at the Superior Thread Salesman who told me, 'just loosen your tension that'll be $18 please'.

I found that even on my domestic machine I had to use a lot looser tension with variegated threads. Not real fond of them.

Sounds like your tension needs changed for Variegated thread.

Adjust the tension....I found this to help with Variegated thread.

I use their variegated thread all the time and don't have problems; however, I aways use the same in the bobbin too. I hope this helps. Happy Stitching!! Debi
