I love Elmer's glue for basting now. Tried it once and it was an instant love affair! I even like the subtle smell of Elmer's...takes me back to my childhood! LOL
I prefer the feel of a quilt with less quilting rather than more, so I seek out batting that only needs quilting 8-10 inches and do as little SITD as possible on MOST of my quilts, but then I don't FMQ on top of that. The very few FMQ quilts I've done have been glue basted.
I'm still pretty terrible at FMQ but it sure is a lot more fun than SITD. I haven't had any problems with breaking threads doing SITD but that might just be because I have terrible control and rarely actually am IN the ditch! I saw a picture of a quilt (on here, probably) that was done in SITD style but about a quarter-inch off of the seam; I thought that looked very nice and will probably try that soon. I think that would help hide how wobbly some of my lines are, LOL.
