Im using Candlewic, 2 larges back to back. It's a 3" madison jar. I'm going to try some more combos tomorrow. Im so sorry about your Kodie. We had a border collie, Buddy, that we lost last year. He was the best dog ever. Cinder came along from a rescue a few months later. We were told he was a shepard mix. He's great with the kids, but recently has started eating our couch. For the life of me, I cannot figure out how to post a picture from the reply box here unless I have a URL. I'll try and put them as my profile picture so you can see them....Well, that is my couch eater. If you click on the profile photo, you'll see Buddy in the snow.
