That is exactly how I quilt. I moved into a small place when we moved back up here from OK and I no longer had a room I could set up my floor frame in. I use a lap frame until we get a bigger place and I can set my floor frame up again.
It's great to see someone who shares the same techniques as me. I LOVE your templates. I'm hoping to find a store that sells them since most everything has something to do with Machine quilting or FMQ and no one uses these awesome templates around here anymore.
