Lots of scraps of leather

Ordered a packet of leather offcuts of eBay.  Was surprised that all the pieces are actually quite sizeable.  One is actually large enough to make a hat brim - only the wrong sort. 

Now I have to decide how to construct the tricorn.  Do I sew of cheat with a hot glue gun?  Do I learn basic leatherwork? 

Oh, what the hell.  I'm making a garment I have no experience with using a material I have no experience with, and a technique that I'm really inexperienced with.  What could possibly go wrong?
