When I bought my machine I had the opportunity to go to a Floraini workshop. They have their their top selling threads in sets. I bought the top 100 most popular colors set of king spools and have never regretted it. While it was a leap for for me to do that, the price was very good and I wasn't always needing more spools in a color I didnt have yet. I love their thread and their stabilizers. Since I didn't have anything, it seemed like a good idea to have a great selection that were all the same kind of thread. They are wonderful products, and their customer service is excellent. What ever you choose I like having the same brand. Now several years later, I'm very glad I made the choice.I did.
