Update on my comment on using the tiny crock pot for scent.....Personally, I am finding mine doesn't get hot enough to fill the entire room with scent. It could be that my pot is old and no longer gets warm enough. It works just fine on the stove as long as one remembers to keep adding water periodically.
I have been obsessed with crochet rugs for quite some time. First, because I saw some rugs years ago and did not realize they were crochet! Second, because they are durable. I had three that my mother passed along to me after having used them for years in her own home. We used them for another few years through raising babies and puppies. We literally washed those rugs to death but it took years of wear and tear. Honestly, I have not found many rugs that can hold up to that kind of abuse.
