As you know, I often "decorate my sporrans with "Military" badges. (they could also be used on kilts ( IMHO ) They have a large selection of Scottish ( Highland, Lowland, Borderers ) Welsh, & Irish.
Not unless you want to cut two "lug holes" in your apron. Most British military badges use either lugs or a "slider" (which also requires a hole) to fasten to the cap/hat/etc.
