Making and attaching the apron

[Lucius Poblius]

I've started looking into making myself a belt (Well two actually - I'm doing the early 1st C AD) but when I got to the apron I couldn't find much information on how it should be attached to the belt.

I was looking in JRMES 3 - The Early Imperial Apron, but there was very little information on how (or if) it was attached to the rear of the belt. It also seems that some of them actually go through the middle of the buckle, and others have rectangular plates on them at the top of the belt ( Reliefs 1, 4, 8, 10, 18 ). There also seems to be something rectangular at the top of the belts as well?

So my question is, could anyone give me information on how to make and attach the apron? Also what are the rectangular bits and what are they made of?

Thanks!
