Leather apron - PEP BB textile.straw.leather.apron

Hah, I found another BB nobody (yet) has done!
Now I'll try to find out how I can make a garment out of leather I can use re-enacting Neolithicum (Late Stone Age), while it fits the description of this 'apron' too. I already made a dress, a poncho, a pair of (mocassin type) shoes, several bags and a pair of leggings (really two things, one for each leg), all of leather, sewn with leather strips or with sinew, no glue or other modern stuff  :-)  But didn't think of the BBs, so not the right photos of the making process.
But first finish my current project ...  

Maybe the pocket will be the problem. As  far as we know pockets on/in clothes weren't invented yet in the Stone Age. They had small bags, pouches, etc. hanging from their belt, it seems.
