I have the Brother SE-350..... sewing machine/emb combo.... I love it..
my few " complaints" are:
1. I am limited to a 4x4 hoop
2. Poor imagine detail on the machine screen
With ur machine being a higher end machine ( and newer-- mine is over 5 yrs old) I doubt u will have these issues..
Mine works fine with the rayon IF it is not a dense design... If it's a dense design polyester is a must. I try to stick with polyester when I can ( more for convience and to keep cost down in not having duplicates)
** interesting to note about the lace needle... FSL is on my list to try... someday, I'll find time
Thanks for the tip~!
