If you mean to guide fabric under the foot, I use a straight pin. I saw that as a tip on one of the quilting programs. The thing I like about the pin is that I can guide the fabric all the way under the foot easily. I never thought about an orange stick. I will have to try that.

Just about anything with a sharp point will work to hold that last 1/4" fabric where it belongs instead of having it wonder off at an angle.

I couldn't quilt without a stylus, but even though a seam ripper or a bamboo scewer works I much prefer a variety I found at a nearby quilt store. I have also seen it in either Clotilde or Keepsake Quilting. It has two "fingers." One is pointed and one is flat. I use both at the same time and often use it so much that I don't even put it down.

I just use a straight pin also. It's a nice multi-tasker.
