We've taken to making collections of usable items--nary a mouse in sight!
The first was a Murano vase from the gift shop in Italy/Epcot. Each of the next five visits included another similar vase, but these were from Arribas Brothers, either Downtown Disney or the Magic Kingdom.
Next we tried the pick-a-pearl at Japan/Epcot. Hooked. Have earrings for myself, sister-in-law, niece and working on making sure each of us have both yellow and white gold earrings and a necklace pendant to match. That ought to take a few years.
And my personal favorite, though we go several times a year, for the trip closest to our wedding anniversary, hubbie "forces" me to pick a piece of jewelry from one of the Wyland Galleries stores (Boardwalk or Polynesian). While of the pieces there are more expensive, there are also some well-priced beauties. Most recent was in December 2009, and was a silver tree frog with gold trim. It was only about $80, but has detail on both the front and back of the frog and can be worn with gold or silver, or both! And that was right as the Princess and the Frog was released, so it has double (or triple) duty as a memento.
