re: Small box for veneering practice

Coming along Dave! I think you are approaching the practice phase the best way, just think about it then give it a try.

Are you cutting your pieces to fit, then applying or do you go oversize then flush up after it dries?

Edit:

Ahh checked out your blog 😬

Might try just doing two opposite sides at a time. Go oversized and trim when dry.
Tape the veneer where you'll trim and  then you'll get a good masking down when you attach the next pair. keeps that glue from getting everywhere.
