What do you use for play surfaces? We are looking into resodding our little back lawn, this is the perfect chance to put a shock-absorbant surface under our wooden playset. But what? Our back yard is only ~800ft, a good ~200ft of which is patio, veg garden and surounding edge gardens. What would not make the yard look very very small? The border garden has barck mulch. I' looking for ideas and photos.
