The first thing you will need to do is get some wool tartan cloth it doesn't really matter what tartan you get seeing as it wasn't until the 18 hundreds that the tartans to different clans were really formed like it is today.Then when you have your tartan lay it out in a large flat area ,and then measure the length across your legs and this measurement will be your front apron.Next pleat the cloth till you get near the end and leave enough for the other apron.
materials: wool tartan cloth, leather belt,leather sting or metal brooch
Step 1: Prepareing for the Belt
This next step is easy just measure from just above your knee to your belly button this will be where you put the belt at. Then i like to mark this by push in the material right there.
