I work alone almost all the time. Working alone makes installing long lengths of crown molding difficult. I am in the process of remodeling the guest bathroom in my home and one run of crown molding is just over 9 feet long. Too long for me to install on my own.
So I bought FastCap's Crown Mold Clip from Amazon.com (set of four clips for under $10.00 including shipping).
I drove a nail in for each clip. Then hung the crown molding on the clips and removed each clip from the nail (which gets left in place) as I drove in the nails.
It worked perfectly and was extremely easy to use. I recommend it. Cheap, fast, easy and works well.
