Crazy Concrete! This conrete is so strange, I just did both of the molds.............on one you can see how many rocks are in every bag. I mixed them both the same, the top one actually has the smoothest look out of all of them....but I could not for the life of me smooth out the bottom one and get the rocks to settle. It's not that the rocks aren't attractive, just that it makes it so hard to smooth them out and make each mold look similar to the last one. We're on our way to Home Depot to buy some portland cement (like Dad recommended:) and some sand and we're going to mix our own. We're going to have to mix it in to the bags we already have because we've already lugged them in from the car, and the mold takes a full 60lb bag....easy to measure since we only have one mold right now. We're playing with this side and we'll get the color and consistency down by the time we get near the patio door. Right?
