Hello all,
I am embarking on the exciting (and apparently addictive) journey of crafting my own sporrans. As you may or may not be able to guess by my forum name, I am a crafter of things... don't ask all what - you're probably not interested.

I've done leather work in the past, but only as an accent to whatever else I'm making. So 'bags' are relatively new to me.

I've been browsing around this site and many others looking at sporrans, and have finally come to a stall-point and need some info.

I'm interested in what weight leather you'd use for the following:
a) stiffening panels and top flap on a Rob Roy style sporran
b) face/body panels of a standard leather 'day' sporran.

I have a whole hide of heavy upholstery (~3oz) grade chrome tanned beautifully finished leather. I also have a 1/2 shoulder of 5oz Veg tanned that I was planning on using for the reinforcing/stiffening panels on the RR and the face/body panels on the standard 'day' type. Do you think 5oz is heavy enough?

Once the 5ox is dyed and waxed it's a bit softer than seems perfect to me, almost like a pannier bag for a motorcycle or a heavy duty messengers satchel. It's a really supple feel, but compared to the POS cheapy I bought to deconstruct as a guide... it just feels a bit 'floppy'.

Should I step up and get some 7oz? or give it a go and risk having too soft a body on the standard? I suppose I could always double up on the 5oz, but 10oz seems like armour plating

Any thoughts would be appreciated.
