One of my all time favorite blocks is the Dresden Plate. It's not a really tough block once you get the hang of making it. I love them all, curved blades, pointed, round. They're just so much fun.
THEME: Dresden Plate.
If you've never made one before, I have to warn you - they're totally addictive, and they'll be absolutely gorgeous as a table topper, or table runner.
Here are a few links to free Dresden Plate patterns. I'm always looking for them!
