ATC Megaswap With a Catch!

I've been wanting to host a swap like this for a while now.
For this swap you will be sending one ATC to each of your twenty partners. It's a lot of work but the cards are sender's choice so you can send ones you already have made or make your cards ahead of time. All media are welcome.

HOWEVER, here's the catch! At least one element of your cards must be uniquely made-by-you. If your card is a collage, it can't be possible to re-create your card completely with supplies bought off the rack.

There are a lot of ways you could do this--you could make your own background paper with inks or starch or paint, you could hand draw or paint part of your card, you could carve your own rubber stamp, you could start with a photo you took or your own digital art, you could add a handmade embellishment of some sort (wire? polymer clay? fabric?), you could even alter existing supplies. The possibilities are endless and if you come up with even more ways to do this, feel free to add them in the comments section!

The nitty gritty (Read carefully!) :
- 20 cards, one each to 20 partners, Sender's choice in both theme and medium.
- Standard ATC size is 2.5 by 3.5 inches. They should be at least card stock thickness.
- This is an international swap so assume you will need more than one stamp to send at least a couple of your cards. Don't join if you can't afford it.
- Every card must have one element that is unique and handmade by you. If this element is not obvious, mention what your unique element is in your note.
- Include both your swap-bot screen name and the full name of the swap somewhere in or on your envelope. This can be on the back of your card, if you like.
- Rating requirement of at least 4.9 and if your rating is less than a perfect five I want a legitimate explanation of all one and three ratings. If the explanation is not either on the rating comments or your profile, then PM me BEFORE signing up for the swap explaining how you got the poor ratings and what you did to try to rectify them. I reserve the right to remove anyone from the swap at my discretion.
- Sorry, but no newbies. You must have completed and been rated for at least 10 type three swaps to be allowed to join. This is a big commitment and I don't want anyone getting in over their head.
