On my way to the airport on Thursday I happened to pass HF. Because I had a few extra minutes I turned around and stopped in - it was my first visit. They had 3 packages of blades so I bought them all because of all the messages on this site. l haven't had a chance to use them yet because all my quilting materials are in the room with a sign on the door that says "enter at your own risk". I plan to reorganize the sewing room after everyone leaves and the holidays are over.
