I think that as they are now (the size I have been making them) they are a little bit too large for an inside use. I am cutting each order as it comes in though, so everything is custom. If you need them just a bit smaller, then I can simply cut them in a slightly smaller size.
As I stated in my PM to you, the biggest problem I have is that I don't have any of the Happ buttons, and I would want to check the size myself before sending out a set. Not a big deal, just something I need to get done.
On the other hand, if RandyT has got something he can offer for these, you may as well just go through him.
