i suggest you purchase 1 spool/cone & try it out---everyone's machine behaves differently and a thread i may have ton's of problems with may work great for you--and visa versa...it has been my (experience) that most of the embroidery threads i have don't work so well quilting===or regular sewing for that matter...but that's just what has happened to me...& not always- sometimes a thread out of my (embroidery threads box) works just fine....i never know why or when- so-if i want to try it- i try it on a (practice/scrap) piece & see how it goes- if it works-great, if not- i didn't mess up anything important & can try something different.
