I see questions on the forum sometimes asking for suggestions as to what to put on these. I have only made a few over the years but after reading a blog post this morning, I think I will try to make a few more. Here is a link to a blog I received by email this morning, I hope it gives others some neat ideas as well. The post is dated June 12th, in case you need to know that to find the pictures.
