it's tough without knowing interests and your budget... but the two youngest might enjoy putting together a birdhouse (or a bat house) and add a book on the subject or some birdfeed. Are they into cooking (6 year olds can cook with some help from an adult)? There are lots of cool cookbooks out there - wrap one and add a box of pasta and some sauce and a little container of parmesan cheese so they can make the family dinner one night. If the 13 year old is into fashion, she might like to draw some new designs - maybe a sketchpad and pencils might work.

But then again, I usually opt for gift cards because I hate to shop. (Think creatively, though, a movie store gift card with a big bowl and some microwave popcorn and a six-pack of soda... etc. )
