Thanks, yes I am not used to machines being quite this picky about thread. the VS machines seem to digest it all. I will say I have a spool of the most gawd awful stuff I have ever seen and feel ripped off to have even Bought it. it is supposed to be the "Good" stuff to. it was advertised as "Bulky nylon" and when wrapped up looks like a heavy nylon thread, when there is no tension on it it is Embroidery Floss. super fine and fly away ... what a mess. however it does work rather well in my 306... go figure I find the thread selection process at most fabric stores to be confusing and inadequate. just a grumpy old man I guess.
