For my signature, I used a great website called My Live Signature. Easy as can be! You have the option to creat a signature from their easy steps on their website, scan a signature into your computer, or draw a signature. I chose to use the creation wizard to create my signature.
Screen 1: Enter your signature. For example, I entered "blessings, Cait"
Screen 2: You'll be able to choose from hundreds of fonts, and see your signature in each of those fonts. Select one.
Screen 3: Select your size by filling in the bubble.
Screen 4: Choose your text color of choice and your background color. (Choose transparent if you do not wish to have a background color.)
Screen 5: Choose the slope of your signature.
Screen 6: Click that you "want to use this signature" and it will generate your HTML code.
Copy the HTML code it provides you and if you use Blogger, you can click on your Settings tab, then click your Formatting tab, and copy your HTML code into the Post Template box. (I'm sure the steps are similar if you use another blog.) Now my signature shows up with each new post I create. Simple enough!
Oh and I'm so excited to have a blog button! To create it, I found a great tutorial here at Mommy Bits. This was so easy to follow. Just what I was looking for! The only advice I can add, is that you may need to downsize the picture you choose to use. (Depends on your picture size, I guess.) But check out Mommy Bits for great tutorials and tips!
Best thing about these two little blog renovating projects? Free and completely DIY. Love it! Good luck!
