Never. I've actuallly tried to get myself to use them, a la Bonnie Hunter, but never seem to remember to... Another option that might work is to just hold the thread behind the presser foot until you take a couple of stitches.

Most of the time when I am sewing triangles. Really helps.

always, if you use the Bonnie Hunter method from Quiltville.com, you can be making two quilts at one time.

Never, never saw the point since my chain piecing always works out OK.....

Always use a leader and an ender. Cut all my scraps into 2 inch squares and use them as a leader and as an ender. Have a quilt top pieced without even trying that way!

I use them anytime I sew.

never, cause I can't remember

I have not gotten in the habit of doing so, but a fellow quilter always uses one and swears by it!!!

I don't like to but do some of the time.

Always and using my single hole plate makes a difference too :D
