I use the Elmer's Glue stick instead of the white glue, then put a clip on it to hold it while I get ready to sew. I don't iron it - never caused any problem with the needle or machine. My Janome MC6600P is my main machine - and if necessary I would go with the newer model 6650. I still have to guide the tail at the end. My friend has a Bernina 770 and she has to hold the end or it wanders. But I believe all machines will do that.
