What size leather to use for wallets?

[hwhleather]

I haven't done any wallets, just holsters and sheaths with 7/8 oz and 8/9 oz leather but I got some 4/5 and 3/4 in for some inlay work and I am thinking that 4/5 would make a pretty nice wallet, what size do you use?

I use 4/5 for the outside body and 2/3 or 3/4 for pockets.

If stamping or carving & tooling I use 4/5 oz. for the exterior and 2/3 oz. for all of my interior parts.  I also have a couple of versions that use Pigskin lining leather for the interior as it offers a better price point for some consumers.  If I am doing a wallet that is not going to be stamped or carved & tooled I will use 3/4 oz. for the exterior instead so as to give a little flexibility to it.

The Shrut & Asch Kidskin at Springfield Leather makes great wallet interiors. It's 2 oz and there are lots of colors.

Thanks guys, also, with that leather being so thin can you even groove your stitch line? Like I said I have only done holsters and sheaths so I don't know a whole lot about making wallets.

Many of us don't groove stitching lines on wallets.  Personally, I like minimalist wallets and go for the thinnest leather I can get away with.  Kangaroo and goat are good and strong even in 1.5 to 2 oz. and make good interiors.  I try to stay with 3/4 oz. for the exterior.  I don't tool so don't need extra thickness.

Scratch line as opposed to groove. Dividers or clamp a straight edge to scratch the stitch line. It's what I do but I'm fairly new to leather.

On thinner leathers, I crease the stitch line and pull it down tight -- no 'groove'.
