In reference to the ENDER....I am happy to use one as having the piece of cloth sewn under the needle will hold the thread from disappearing when I start the next line of sewing. Thus no re-threading the eye of the needle. Bonnie Hunter uses one, it is from a stack of pre-cut 2 inch squares next to her machine. The little squares can be used in another quilt. She will also use them to help her keep track of the number of chain sewn items....10 or 20 like items is enough for her.
