450 pounds of moss rocks, individually selected. 225 pounds of rainbow jasper, individually selected. One bag (maybe 100 pounds?) of large river cobblestones. And, the biggie, six cubic yards of shredded bark. (That's 81 of the 2-cubic-foot bags, if we were buying bags.) Part of what will replace our lawn (which I've removed ab. 80% of so far, by hand, day by day...). The bark is 75%+ of the total cost. (We have some drought-tolerant plants and will be buying a few more. )
