On the Mall Crawls & Shop Hops online, once you sign up you have access to their list of shops, then you visit each website & try to find either a block (for the Mall Crawl) or the bunny (for the FabShopHop). Each one has it's own set of rules about how many you need to find to qualify - the FabShopHop has prizes of gift certs up to a sewing machine. The other cool thing on the FabShopHop site, they have a fabric finder. You put in a description & it comes up with places that may have it.
It can be addictive! I try to have my credit card locked up when I do it! LOL
