I just took a Craftsy class on FMQ and that instructor said not to SITD beforehand because FM can create puckers against the pre-sewn seams this way because the fabric is contained by the SITD but is being pressed out by the FM stitches. (Didn't explain that very well....)
How do you all avoid this? Or is it not a problem?

Here's a blog post about it, although she doesn't talk about the puckers here:
