This tip is probably known by most everyone, but I had need of it today for holding just the corners and one edge of a cover while the glue was drying. These binder clips come in different sizes and really hold tight, tighter than a clamp for small jobs. I like the way the look, too - simple and efficient. Too bad other little day-to-day things in life aren't that way!
Also, I discovered a new material (see pic) that improved even on the diagonal stretch cord (in my last post) for holding iPads - am still trying it out but it looks good so far. More soon.
