Here are some quick links on the lore of Fish Extenders.
What they can look like,
Original style
bought from ebay or made by fellow diser (good searches include; Mickey Pockets or
Fish Extender)
Homemade
No sew instructions
The Fish extender, original purpose was to accept all the treats/gifts dis'ers were giving each other during a Panama Canal cruise. Nothing to do with
DCL at all.
The Fish..near your door, the permanent thing is to accept mail from DCL (notes and such).
epcotkilterfan found those wonderful mickey hanger with pockets and thought it would be cool, since so many people were bringing gifts, the Dis'ers needed more room than just the fish to deliver them to. She was right...the cruise was like Christmas morning, every day..lol.
Now many cruise meet groups decided to have FE exchanges. I have a great Tinkerbell FE, it is bright lime green, lol. I have done magnets, lollipops with a souvenir pillowbox, on a longer cruise a group of us (13) got together and had mouse-pads made up (there were 103 families cruising) and we gave 1/family. I can be something small indicative of your local region, I got a moon pie once, and candy from speciality companies, lip balm, highlighters, customized silicone bracelets, personalized pen/pencils, pirate stuff, mixed CDs and cruise themed bookmarks. No matter how big or small, always a treat to find a surprise in our FE.
Now I will sign off, until Monday when I actually have the cruise booked. Called DVC today and they had no clue what I was talking about,
