When I was a kid (back in the 1960's) we would go to these little souvenir stores in New Hampshire that specialized in pine stuff. My favorite thing they sold were small pillows, maybe three or four inches on a side, that were full of pine needles. They smelled wonderfully piney. I'm pretty sure you could get them up to at least a foot square. Here are links to some sites that sells them - http://www.balsamfircreations.com/ and http://www.maine-lynewhampshire.com/pc-390-75-new-hampshire-balsam-pillow.aspx.
The other thing they sold was pine incense and a cool little log cabin incense burner. The "cabin" lifted off of its base, and the incense, which came in a fat, log-like stick about an inch and a half long, was lit and placed on the base. When the cabin was placed over the burning incense "log," wonderful pine-smelling smoke would come out of the tiny cabin's chimney. Here's a link to a place that sells them - http://www.madmoose.com/incense.html, and here's a picture of one:
