I got those buttons from buttondrawer.com, a site someone mentioned in another thread. I googled "Celtic buttons" and that site popped up. They've got an entire Celtic collection.

Thanks for the compliments, gents! I'm very excited to wear this with my Macduff Red to Mass on the 15th.

And there's been a ton of talk about folks wanting to get a jacket converted. If you're going to do it, vmac3205 is top-shelf.
