Special limited editions we designed by commission for a one-time use or private customer are also listed here. You can see some of them among the Special Editions categories in the Search Index. Others may become products eventually.

A growing number of custom designs by Kate were made or printed as collectors' gifts only. You can find them in the IPP and Gathering for Gardner write-ups.
