Now that you have a built-in cone holder or 2, you need to go to Connecting Threads and get yourself the whole line of threads on the cones. Their thread is wonderful - almost lint-free!!! 5000 yards for $9.99 Comes in a whole range of neutrals from black to white and all in-between. I'm on my 2nd cone of cream.
While there, you can pick yourself up some of the most luscious, silky batiks for only $5.96 a yard!
Congratulations on your new baby. I have the 6600 and I think my favorite feature (there are so many) is the auto thread cutter!
Happy shopping. And many hours of happy stitching.
