I have lizzie and I use metroemb if customers agree with poly thread no lint. any of the polys leaves next to nothing lint. I also use the spun polys that actualy look like cotton. lot less lint there too. there will be no lint free threads as longarming creates its own lint from top batting and backing all made out of cotton. Hope this helps. p.s. Tin lizzie is considered a longarm machine anythign under 17 is mid and anything under 9/10 is dsm
