Same here. I've got 2 portfolios - one for interior work and one for exterior work. I usually bring them with me and only use them for design ideas or if the HO specifically asks to see them. Most cases the HO has already seen pictures of our work online.I've sometimes used ny picture book to answer specific points- we will discuss how to deal with a particular area of the kitchen, or some particular need of the customer, and then I say, "how about if we do something like this?" and then show them that specific photo. That seems to go down well. Quite often they say "can we look at the other pictures?" and of course I agree.
