I tried to get my g/f in Canada interested in Digi~scrapping and explained the entire concept to her. She then said she thought it was too expensive for her. I told her if she's willing to put in the time, she can find everything she needs by looking for the freebies.
That may even be an idea for a GDS challenge.. a page made from only the DD... hehe..
Anyway - I think all the credits should go to the designers who do all the work and I strive to use only material where I know who's done it so the credit goes to them. All my photos I take myself (or hubbies/kids) - because why would I want to scrap photos from the internet? shee.. These are my memories - not some strangers. Anyway... I think common sense rules and most people will do the right thing.
