Be sure to to a bit of testing on a scrap quilt sandwich to make sure you are getting the results you want before you start on the quilt. Needle size , tensions, and bobbin thread all play into the quilting results.
I like varigated threads for FMQ. I just did a Christmas quilt and found a red, green & white one. It worked perfectly. I used it in the bobbin also. It is a Signature thread but it is 40 wt so it is not as thick as the Signature thread that Lori S mentioned.
