there are so many different threads on the market to try- i understand (sort of) the whole if it works...
but i also believe you should try new things when you have the opportunity-
long arm quilters are quilting wonderful quilts using all kinds of different threads- rayons, silks, cottons, blends-lots of choices-
when ever i have the opportunity to try a new thread i give it a try- if it works for me i make note what it is- where it came from- how much it cost- how much is on a cone ect...
the more choices you allow yourself- the further your quilting is going to go...be adventurous along with creative!
