I constructed PALIO out of stuff bought from Costco (the trailer), the local potter's supply house, and Home Depot. This year I'm not going to do any real large-scale art but I'm making little enhancements and geegaws for my personal campicile. These will most likely be comprised of materials gleaned from all over — dumpster diving, HD, Michael's, Ben Franklin Crafts, Fred Meyer's, the forest, Costco, Bi-Mart, Jerry's Home Improvement. I tend to just walk around and be "the seeing eye," looking to see what's what, what's where, how it can be implemented.
I hit thrift stores and always take a run by the clearance tables whenever I'm out on an errand. A dollar spent here, fifty cents there, next thing I have a virtual treasure trove of just <i>schtuph</i> collected over the years. I never throw out dishes when they break, they go in the "ceramic shards" box and get made into tile mosaics along with shells, glass shards, marbles, sparklegems, et alia.
I haven't been signed onto Freecycle for long but I'm pretty sure it'll be a major factor in the Schtuph Collection this year. The Eugene Freecycle numbered 10 when I joined: it's up to 402 when I checked a few hours ago. They ran an article in the paper a week ago and the next day it was 275 — it's almost doubled in one week!
