The Experiment Series: how to collect Stitch's experiments

Stitch is Experiment 626, but he is far from the only one. Our Experiment Series gives every experiment its own pin, so you can build the collection number by number.

Start with 626

Most collections start with the original. The Experiment 626 pin is the anchor of the series, and there is also an Experiment 626 keychain if you want to carry him every day.

Organize by number

Lay your board out in numerical order and leave gaps for the experiments you are still hunting. It makes missing pieces easy to spot and turns the board into a checklist.

Add crossovers

Once the core series is going, our crossovers put Stitch into other stories, from villains to princesses. They are the pieces that make a board feel personal.
