I've just made them as new addon's, that way they work the same way as any other crafted addon, the one thing i have managed to do tho, because of the way i've made our shards ore & granite and used the existing craft system, i can basically now create anything in addon form and just add to our craft menus, since the normal system picks up the hues anyway.
If i get the whole thing finished i'll drop the files in here, but the way that i've changed our craft system might not allow other systems that are already out there as downloads to work.
Something else i've managed to do tho, is make new sets of runic hammers and sewing kits too, which again, all work with the existing craft systems. This has help'd me to make a few changes to our shards BOD system too and also create a new set of runic scale hammers too (although i'm still working on a BOD system for scale's).
The reason i went down this path was although theres some good crafting systems out there, they all seem to work in there own ways, ours works with the systems which are in place already, a quick example would be something like the lost alchemy, which was a really good idea, but wouldn't allow me to put the potions into say kegs, so i've added that also into the normal alchemy system (with just a few minor changes).
I'm not pulling others work apart here, i've just tried to stay on a standardisation type way of doing it, which in turn allows the adding of things like addons for example, to become craftable too in all of the colours the system will allow.
This has been in the works for quite some time, normaly because if you make alterations in one part it usually effects something else, so it's just been a case of pulling it all into line for the end result, but now i'm begining to see the benifits to myself when anything needs to be added to crafts, basically all i need to do now is just go into the craft definitions and add the new items in the right menus once there own codes written, (just like adding new items now).
I guess theres a lot of ways you can create a new craft or craft system, my choice was just to use the existing one since it did most of the important stuff already.
*EDIT*
yeah i know what you mean tho, you want to see where some people try putting the Gothic Column's on my shard...lol
