When I made my little blog button (below), I used a variety of tutorials to help me out. Since then, I've shared my little collection of resources with several other bloggers. Since digging up that email every time people ask isn't the most efficient thing in the world, I'm doing a little roundup here (it's sort of a mini roundup actually because I didn't use too many resources). So if you are looking to create your own blog button, here are some tutorials that might help!
Musings of a Housewife has a tutorial here for how to design a blog button and then another one here for how to create the code for your blog button. I think these two might have been my most favorite resources for creating the blog button...
Though I used this one from Empty Easel as well because I kept having issues getting the actual button itself to show up above the scrolling box of code.
There's this one from one of my most favorite sites - Kevin & Amanda - that I used. I always check there for blog-related tutorials because I've loved everything I've found there!
Then there's this Squidoo lens page that I found... it was linked from another tutorial I found then, but can't ever seem to find again and give proper credit to. I also looked to this one when I was having issues getting the actual button image to show up.
And finally, there's this tutorial from Blogging with Amy (another excellent resource for general blogging tips - as in, not just for crafty bloggers) that I found useful.
Now these are newer resources I've found to help and think might be even more useful (I just didn't have the good fortune to find it then)...
Here's one from Mommy Bits (with an awesome walk-through for creating the code), another one from Who Are You Calling Crafty?, and one from Sew.Craft.Create. (part of the Blog Design 101 series).
Whenever I've sent this out, I've reminded bloggers that there are continually more and more tutorials for creating your own blog button so you might find your own best ever option by doing an good ol' fashioned Google search!
