No Desktop icons after Boot

After booting, I have no desktop icons. The /home/userid/desktop directory is intact and I have the taskbar at the bottom of screen. I am using KDE. How do I restore the icons?
Thanks in advance,

Right click the desktop select folder view settings. You can reset things from there.

Thanks for the answer, gogalthorp…

You can also set your desktop up in a widget, Unlock widgets then select add.
