Presumably it is to be a permanent feature on your glengarry, so perhaps it could be made to look a little more than it is by making a needlework setting for it using something like a patch of ribbon to create a different texture as a background then creating a ring around it using gold or some suitable colour of cord couched down so that the overall effect is something like the belt on the clan badges to enclose the irregular outline of the badge.
That would enhance its impact considerably and should not be beyond most people handy with a needle.
