Questians regarding making your own sporran

[Brasilikilt]

Hey all

With my USA Kilt due to arrive in the next few weeks, I'm definitely going to need a sporran of some kind.
I have made lots of things out of leather such as knife sheaths and shooting bags for my flintlock, so making an adequate sporran is certainly an attainable goal for me.
I was wondering about a few things such as where I might find some sources online to look at patterns and/or pictures of sporrans of varying styles, just to give me a better idea of what will be most functional and attractive and also easy to make. Is there a museum website perhaps?
What thickness of leather seems to be most common?
Any other sporran makers in the house?

I appreciate any suggestions
