Invisafil thread
 

Has anyone tried this for SID. It is 100 wt polyester. Made I think, by Wonderfil. I'm not fond of those monofilament threads.

My best quilting friend used it on her log cabin and had no issues. Good luck! Do not wind the bobbin too tight :)

I've used it and like it ... if you don't stay in the ditch, it's not as noticeable as a heavier weight thread.

They also have an 80 wt thread called DecoBob ... a little heavier, but still a long way from a traditional 50 wt.
