Need Gift Help (a bit long)

Every Christmas we have to get BIL's girlfriend gifts even though she does not celebrate christmas morning with us, but rather, comes in the evening for dinner and runs to open her gifts first. DH hates BIL's girlfriend but we always try to get her something she would actually like.

However, there is not much about her this is what I know about her likes:
-her cat
-purple
-socks
-making jewelry
-chocolate
-scrapbooking
-reading/books (she works at a bookstore)

The past two Christmases we have already gotten her:
-purple socks
-purple scarf and glove set
-chocolates
-framed photo of BIL and her
-a fancy bookmark
-a jewelry box
-scrapbooking kit

We are all out of ideas. Any suggestions, please??

maybe a gift certificate to a craft store?

if she has a kindle, you could get her an amazon gift card so she can buy some books with it ... if she does not have a kindle, you could say that you're putting money towards it

if she has a house / garden, you could get her a stepping stone for it like this: click

How about a sweatshirt with cats on it

something like this


Maybe you can find something that looks like her cat


ETA
Look they have this in purple

Maybe a pretty porcelain cat figurine
Gift certificate to Michaels?
A few different books from genres she likes
Gift certificate to a favorite restauant

gift certificate to michaels or ac moore sounds like she would like it..

or maybe bokos on crafting
