There is a "gadget" for that. I have needed to purchase one, but I've been too stingy with my pennies. LOL! With all the money you saved, you could probably buy one without too much guilt.
It's called a Deely Bob.
Is this what you needed?
And WOW! The search I just did came up with much better prices than what I had found a while back when I was looking for one!!!!!
