First, some Holiday Mini Catalog product information. Here's what Stampin' Up! said (with minimal editing by me):

You may or may not have noticed that we've chosen to carryover
several products from the Holiday Mini Catalog. This list of products
(shown below) is available for purchase now and will be available in the next Idea Book &
Catalog.

As usual, there may be additional products from the Holiday
Mini Catalog (not currently listed) that also may
appear in your next Idea Book & Catalog.

Note that the Charming set is the one that was created as a jump-start for your stamping a focal point for your Simply Adorned jewelry.
