I do both also...I can FMQ lap and crib sizes comfortably but rent a LA for larger projects. It all depends on the pattern of the quilt. I used wavy lines on my last crib quilt with my walking foot and often do cross hatching on kids’ quilts that will get a lot of washing. [ATTACH=CONFIG]603631[/ATTACH]
I still consider myself a beginner FMQer but I enjoy the process.
