<p>as far as hanging stufff- i suggest the 3m command strips for poster hanging. You can buy a pack of 12 - at walmart for about $2.00 they work much better than putty, you can hang more than just posters - right now I have my surround sound speakers hanging, and two paintings.. and two posters too. here's a link <a href="http://www.shoplet.com/office/db/MMM17024.html%5B/url%5D">http://www.shoplet.com/office/db/MMM17024.html</a></p>
<p>i would stick away from the putty stuff because it's very tempramental and you never know if it will stick or not. at my school, blue stuff worked, yellow stuff didn't, and white stuff did occasionally.. it also has a tendency to gunk up your posters. all of the moisture in the putty managed to seap through and ruin the edges of my posters after one year.</p>
