Using normal weight for org strike-through

[fatiparty]

I am using the following code to change the colour of emphasis (strike-through).
But I also want to use normal weight for the font.  How can this be done?

(defface emph-strike
  '((default :inherit (:strike-through t))
    (((class color) (min-colors 88) (background dark))
     :foreground "#ae6029")       ; CR: 7.08
    (((class color) (min-colors 88) (background light))
     :foreground "#ae6029"))      ; CR: 7.03
  "Colour typeface for strike emphasis.")

(setq org-emphasis-alist
      '("+" emph-strike) )
