Question concerning regimental cap badge mounting

[Nanook]

My question is how do they mount items like this? Do regimental glangarries have grommeted holes for the mounting or do they just create holes as needed.

To add.. holes are sometimes punched just into a backing but often through the whole cap. Some people add a bit of leather support to the back but its a bit more complicated since different regiments/divisions have different backings on cap and bonnets and there seems to be many different styles and traditions. While it seems that most cap badges have very large split pins to keep them in place some don't. We need also recall that many items would not issued but purchased at an officers own expense. Patterns have also changed so if one wants to keep to period its not that easy. There are also differences at different times betweens between Glengarry cap and Balmoral bonets. There are also some conventions. The BW, for instance, has no tartan backing and only the Glengarry has a badge but both have a red hackle.. so now the quiz questions of the day: "If the BW have no tartan backing on their Balmoral bonnets and have no badge then how do they mount their famous red hackles?" :-)

I use several large safety pins through each lug. That way I don't have to punch holes in my Glengarry.
