This is the shade we had...it showed everything, including sweaty footprints. It looked beautiful right after it was cleaned. It didn't stay clean for long with 2 kids under the age of 5 running around.
DH just said that the floor has to be 1/8 to a 1/4 inch away from the walls. Tape the foam padding (moisture barrier) down to hold it in place and it will go easier.
We put baseboard molding down after the floor was installed. Don't put it flush to the floor; leave it up about 1/16 inch. Just make sure it isn't pushing down on the floor.
DH is very handy; he can do just about anything in the house home improvement-wise. However, my friend's husband is not handy at all and he installed the laminate flooring by himself. The hardest part about this flooring is getting it started.
