Then pick up the doily, squeeze, wipe off the excess. Lay it over the mold to the right position (any position you want it be). You can wipe off or add extra cement even before press the doily to make the concrete additive to it.
Then wait overnight, and the molding is ready. Yet this thin cement doily is easy to get crack, be sure to mist everyday before tapping it down from the mold. Let it dry for a couple of weeks to hard completely. Now you can have the surface treatment by sanding and painting to your favorite colors.
Now you can create whatever shape you love to make perfect planters, even your crochet hats will do!
