Wood stir stick
Trace your template on a piece of cardboard. Follow this template by using a triangle to create your own.
Cut out your template using scissors (or an x-acto knife).
Line the interior of your cardboard mold with packing tape to keep the cement from seeping into the cardboard.
Tape together your mold, securing the exterior of the cardboard with duct tape.
Mix your cement according to the directions on the package. And scoop it into your mold, filling it to just below the rim. Allow the cement to dry overnight.
Remove cement, which will be mostly dry, from the mold. Insider tip: To smooth any rough edges, lightly sand your table number with a medium grit sandpaper.
