After the top was done I had to attach some anchors to the base so as to be able to attach the top. There are 8 of these to keep the top flat and anchored properly. I glued and screwed them to the skirt.
In this picture you can see 6 of the 8 attached.
And then the final 2.
A better view of all 8 attached.
Now the top is ready to be attached. Next I will make some drawer pulls.
