I've tried 2 different threads as I can't find too many choices and they both tangled around the end of the spool during the quilting process. I'm using transparent because I have to get this quilt done and started hand quilting about 8 months ago and have to finish by 5/30/12 for a birthday gift. The thread seems really thin and wispy and is very hard to machine quilt, ie., pulling up the bobbin thread, etc. I've had to restart the process numerous times and am getting very frustrated. Does anyone know of a thicker nylon thread that won't tangle and wrap around the end of the spool? Any help would be appreciated.
