Not sure how critical you want us to be of your site but I'll be honest and upfront. First off, I like what you've done. I did visit your site and with the exception of a few typo's it looks really nice and I like what you've done. Here's an example of what I noticed.
Underhill Custom Creations is a family run business started by John in 2008 when he began his adventure in
(to) wood turning and resin
cas(t) ing. He is
know(n) as "JohnU" on the IAP (
Penturners.org) and is a long time demonstrator and current co-coordinator of the Penmakers International MPG.
Underhill Creations is know
(n) for their (domestic
(ally) raised) Real Bird Feather
(s), Snakeskin, Opal, Cardistry, Candy Wrappers, Military Buttons, Watch Parts, Color Casts and Embedded Object cast pen.
Did I catch them all, probably not but you get my drift and I was terrible at English so I could be way off too.
Here's just some advice on something that happened to me that hopefully you won't experience. My website address is Wolfcreekknives.com. A guy asked me if I would sell my site name to him, I told him "no". He offered me $12,000.00 for my site, still NO. So what he did was to use the name "Wolf Creek
Custom Knives" on Facebook, not much change and people thought we were the same. So I started getting a lot of complaints about his work, most of which was not custom as he bought his blanks from the same supplier I did. Needless to say he's no longer in business, which is fine by me. In your case you're doing something totally different but I'm afraid you might be perceived as the other company and if they start messing up it might (big might) impact you. I feel you really need to differentiate yourself from the other guy.
I don't do anything on Facebook so I can't speak to how well it works etc.
I will say that after viewing your site I'm more than impressed with what you're doing and your product line. I just need to get more involved in blanks other than wood. Please take my criticism as a compliment and that I only want to see you succeed at what you're doing, you've got some very nice items.
