I too wouldn't use duct tape. While I know you wouldn't like trying to get it out of your carpet, it may cause a terrible mess on your quilt. I would look into using the library, or a community center, your church, or a sewing circle that may be close to you. I've use packing tape and I have used pins. Figure out what works best for you, I'm with you though, getting down on the floor is not as easy as it was before 2 knee replacements.
