Decks that you don't want to shuffle

For one reason or another--the deck is too big, too fragile, too stiff or sticky--most of us have a deck that we can't or don't want to shuffle. What method do you use to make sure the deck is properly mixed? For example, I've been dealing such a deck out into 7 or 9 piles and then randomly picking up the piles. It's effective, but tedious. What other ways might there be?

I usually lay the deck on to the spread cloth then just mix them up in a clockwise direction. I do this with all my decks, as my hands are so damn small and I never learnt to shuffle properly

I have tried and just cannot figure out how to shuffle my Light and Shadow deck....the cards are HUGE, squarish, and they stick together.....

It is such a shame, I would LOVE to work with these cards, maybe I need to get some of that powder....(forget the name!). Any other suggestions???
