I wanted to share this link with you. Click here to go to the site. It is a blog, that gives you steps on how to make a blog button and then the share box so others can take your button. I am working on one, I wish I knew how to make it match my blog, but I am not sure since I used a blogger template. Maybe for my 6 month blogaversary I will attempt to redo my blog and have my button and blog match. :)
I hope this link helps you!
Have a fantastic day!
