I've Got A Notion!

What notion is your favorite and how do you use it?

I really like my hem clips. You know those little metal clips that look something like a clothes pin. I have not only used them to help hold hems in place, but have used them as extra hands for other projects as well. Glueing paper projects that need to be held in place, temporary fittings for garments and to hold patterns to fabric when marking. Gotta love those handy dandy notions!
