I'm a big fan of radical goodness. And so of course, I love the wonderful knitta please and their guerilla crafting efforts. Well now I can add guerilla gardening to my list, with the discovery of seed bombs thanks to apartment therapy ny, via heavy petal. "Seed balls are useful for seeding dry, thin and compacted soils and for reclaiming derelict ground (which is why they are often used in guerilla gardening). I like 'em because they're easy to chuck over fences into empty lots." Love it!
