This evening I had some time and took your advice and created a Facebook page " The Alley Kat Hat Company" would you do me a favor and search that, and let me know you found it. I have a lot of work to do to build it up, and link with others. But started my portfolio there tonight. Give it a look if you don't mind. Thank you!
I just did a search on facebook for 'Alley Kat Hat.' I got a number of hits but nothing that was definitively, without a doubt, your company.
If any of those hits are you, I would redefine the title as 'The Alley Kat Hat Company,' and then begin posting photos and descriptions of your finished hats, as in - the ones in this thread, to as many vintage men's wear pages I as I could find (I've never seen a post from anything called 'Alley Kat' online before I just did a search just now). That's how I have been learning of many of the different makers of repop 'vintage' stuff out there.
Anyway, that's what I would do.
