How to insert symbols on blogspot, before "blog archive" and labels, such as arrows, little balls etc?

The gadgets "blog archive"and "labels" are already working properly on my blog (blogspot). But I'd like to see/insert, symbols such as arrows, for example, on the left side of the month (blog archive), and, maybe, little circles, or stars, besides "labels"(which are ordered on a "list", btw). Help, please!! Thanks.
