These are two companies that have a strong presence on the internet. They also seem to be one and the same. We say that based on the fact that the P.O. box address is the same for sending in order queries. The fax number is also the same. And there are some product are in common.
While Christian miniatures has crafts that involves making miniatures for books like The Bible, Book Of Hymns and such Tiny Details has the same books and a host of other miniatures such as dollhouses. Christian miniatures has a couple of other products such as a jigsaw puzzle and a miniature hand fan. All of these can be found on Tiny Details as well.
Why this company is operating under 2 different aliases is hard to guess, but it does arouse some curiosity. There is no address on the website of Christian Website except for a phone and fax number and a P.O. Box address. They do not list a physical address. But the Tiny Details website does have an address provided as well.

Christian details charges $55 to register. They send you the supplies and samples for this amount. You must first get approved in order to start making the whole batch and they ask you to send in jut one sample for approval. If not approved, I surmise you are allowed more chances. But this is an important question and clarify it with the customer service when you call.
Another question to ask is the physical address of the company and whether it is the same company as Tiny Details. We are curious as to why a company chooses to work under 2 different guises and you can ask them this.
A batch of finished miniatures comprises of, typically, 100 items. So you need to assemble a 100 miniatures before you ship them to the company.
You have 60 days from the time that you are approved to finfish your batch.
If you require extra material to finfish, the company claims that these are dispatched to you at no extra cost.
The $55 is refundable. Although there are a lot of terms and conditions to this.
Read about it in the FAQ of the website. But we gather that you have to keep buying the supplies from them every time.
