Last May I noticed an announcement from a friend of mine that his company, The Theme Foundry, had released a new WordPress theme, called Make. I didn't give it much thought at the time. Most of the sites I build have custom designs, and I usually start with something like Underscores, or no theme at all. Then last fall I decided to switch my own blog to WordPress, and needed a theme, and didn't have a design. I tried out Make, and quickly fell in love.
Before I get too far into this, I'd like to point out that Make has 2 URLs you should check out. The free version of Make is in the WordPress.org theme respository. There's also Make Plus at The Theme Foundry's web site. Make Plus is actually a plugin that greatly extends the Make theme, and costs $99. It adds lots of functionality and comes with support, which is great.
