Gap between layers

[HandyDave]

One mistake i made i hate to say several times but it was several times when i was first starting out was beveling my edges and i ran down the whole inside edge where it was to be glued to another piece. This will leave a pretty good vally that is hard to sand out speacially if you keep stitch line close to edge.

G'Day,

When I'm making knife cases for  leathermans for example, put both pieces on the bench sander to smooth the edges before gluing,   and I make sure the contact adhesive is covering the very edges and then use paper clamps all the way around ( briefly) . Then sew , sand, and burnish.  I have used some old hard boot polish to fill in any minor gaps, burnishes quite nicely too.

Good point! I have definitely made that mistake before, but fortunately not still the issue. 
 

follow up to that - if I’m making something that I’d like to be slim or slimmer, like a minimalist wallet, I’ve seen people skive the edges of the pockets down, I would think that’d end up making a similar issue to the one you just described. Any thoughts on that?

If your skiving is smooth and even, it should not cause a void or valley of any kind.
