The problem:
We have very limited inventory space for our own items let alone to keep our glamour items that sometimes are expensive crafts or random drops.
Because of resource limitations, the addition of more inventory space has been denied to us thus far.
As a consequence we have to throw glamour items away thus throwing away all our effort.

My Suggestion
So what I propose is the addition of a Glamour Book.
A book that could work a bit like the sightseeing log, except that instead, it would keep a record of certain "unique" items models that we have owned and bound before.
For example, a Foestriker tabard drops, it would then be registered to this Glamour Book.
Then, rather than looking for an item in our inventories, we'd be given an option to search the glamour book when using a glamour prism even after throwing the item away.

This book would be usable only with glamour prisms and the "try it" preview, it wouldn't provide a hard copy of the item.
