Sharon,
To get you by until you can order some of the same
needles that I sent to Krystyna you can buy ANY brand
Top Stitch SHARP needle; but you only get 5 needles to
a package and as you may know those 5 needles can cost
anywhere from about $.400 and up.

I buy my needles from allstitch.net for $26.69 per 100 needles.
From my own personal experience I found that using ONLY the
SHARP point needles for everything (including lace) has eliminated
97% of my issues with embroidery. The other 3% I found that I had
to use a BALL point needle for stitching on items such as t-shirts or
knits.

I use the 75/11 & 90/14 the most and sometimes I use the 80/12
although not as much as the other two.

Something else I found that helps TONS with embroidery is using
thread nets on ALL my spools of thread, it helps to control how much
thread is being unwound at a time. I started using the nets only on
my metallic threads, but soon found that my thread did much better
when I used the net for any kind of thread.

Hope some of this information will help you.

So, I really need to cancel my order for the polystar? It's just weird, I've had some good days and bad days with the threadart, mostly bad days, but never with the brother or polystar. Go figure

I've used Thread Art and had a problem with my machine until I changed the needles. Do a Google search and you'll come up with tons of sources. Here's one. I wish I could remember where I bought mine, but am a little brain dead at the moment.

I just bought a Janome 350e...I pick it up next week...can't wait!

I can get Organ needles from All Brands (we have a local outlet here). As far as the thread goes, my PE-770 does not like the red threads from DesignsbySick. I have to use Robison-Anton or possibly Coats & Clark, but it sometimes doesn't like the Coats & Clark. I got a large spool of red embroidery thread at a flea market, and it has no problem there. Can't explain why it just doesn't like certain red threads.

Have you checked the Robison-Anton thread at Sears. It's only 3.99 a spool and that's cheaper than any place I know at the moment. I stocked up on it some where this quilt shop about an hour away had it on sale 2 for 6.95. I would go every couple of weeks and get more. The last time I was there they said after months they no longer had the sale. I was bumbed out until I saw the sign laying on top of the display. I pointed it out to the sales person and she gave me the sale for one last time. Wished I'd had more money because I like 2 for 1 sales.

My Viking Ruby hasn't had a problem with any threads except for the serger thread. Once I went up to a size 90/14 sharp needle it did great; no more broken thread. I was stitching out FSL and since it was for kids I didn't want to spend a fortune of thread. I like the RA thread, I've also used Floriani thread, sulky, Prencia and they've all worked out really well. Maybe you could sell your thread to someone who doesn't have a problem with it. I've never used it so I don't know if I would even though I never have. I start off only buying a few of a brand to make sure it stitches well before buying more. It's like designs; I go for the freebees to stitch out before I'll buy (at least for full price) the designs and find out I have a problem. I did learn last night though how easy it is to change the density of a design and that'll be a great help. I like to resize some things and when making them smaller the density can really affect the out come.

I also have the PE770. I use the Threadart and have no problem, I also have Coats and Clark and Threadelight. (variegated). I set all my spools on a separate stand and feed it from the side. Don't know, if that makes a difference, but it can't hurt. Don't give up, try again, tell your machine that you are the boss!

With touchy threads I use the attachment to keep the thread vertical on my PE770. That helps a LOT.

From the first day I started having trouble with the thread, immediately I brought out my thread stand. While waiting for my machine to be delivered, I read everything I could find here on the board in regards to the type of machine, threads, tips and all to prepare myself. I remembered reading about some having much success with a thread stand. At first it worked great, but here lately, no matter what I did, the breakage was getting worse, but only with threadart.
I'm going to try the suggestions given here and hopefully things something will work. :)
