Deb, this same company do Invisafil which is 100 wt - it's only available in neutral colours but lasts forever in the bobbin. It's also great for machine applique. I'm a bit of an evangelical convert to these threads - I got a sample pack at a show and the range and quality is unsurpassed - no,I'm not on commission! LOL

I have used the veriegated thread lots of time on my LA, and I love the results. I do not like coats & clark thread. It has a wax coating that my machines don't like. I sometimes use a pure silicone spray directly on my thread spools, if they don't play nice. This really does help.

I use it top and bottom all the time with the Gammill. Some times I have to go around the tension spot twice, intsead of once but it depends on the thread. I rarely put solid colours on my quilts. No issues so far...

I always use the same thread, top and botttom. never a problem, except that some varigated thread breaks easily. If a thread does this on my practice quilt, I just stop using it. I don't even try to adust any tension. For me, finding another thread is easier than playing with the tension.

peace to all

I can do it. The thing you need to keep in mind is to make sure the thread weight is equal in the top thread and the bobbin thread. :) I have two Gammills.

I use variegated top and bobbin quite often with no problems. I have a Gammill and the thread I like is Signature 40 wt.

My mistake - Invisafil is actually available in 30 colours. :oops: :-D
