How to Make A Button for your Blog

I have done a lot over my many years of blogging (I'm entering my 7th year!!) but I have yet to make a blog button. 

If you are ready to make your own
blog button, Jess at A Few of My Favorite Things has a very comprehensive HTML tutorial for you. 

If you make one, please post below so I can admire your creative handi-work!

I think party I have not created one is because I'm not really sure how I would use one. Do you have one and how do you use it?
