The situation is this.
I have a form and on it a button. When the user clicks the button I want a new form to open, the user to select something from that form,accept the selection, and then the main form to continue execution using the item previously selected.

I'm thinking threads, but how?

If you want to do this, you don't need to do any thread blocking. All you need do is open the new form as a modal dialog, which pauses execution on the calling code until the dialog returns. Here's a typical flow:

private void ShowMyDialog()
{
  using (MyDialog dialog = new MyDialog())
  {
    if (dialog.ShowDialog() == DialogResult.OK)
    {
      MessageBox.Show(dialog.UserEnteredValue);
    }
  }
}
