The OT RULES!!!!
I'm glad it's working out.
I think you should maybe agree on a set of covers and then design the case to match and/or complement.
Until you tell me how many Amaray the case is to hold, I won't be able to give you the dimensions for the spine or top but the sides panels for an Amaray case need to be 1659 X 2300 pixels @ 300 dpi
These dimensions are for full coverage: edge to edge and top to bottom of the 3 main panels. If your design calls for an empty border around the artwork, you should allow for it.
On a side note, it would be important to get an idea of how many people are interested in getting a case. If we get enough interest, I'm prepared to cut you guys a deal. A numbered and limited custom case usually runs between $40 and $45, but again, if we have enough interest, I'll keep the price @ $30
I hope this will help the project get started.
And thanks to you for stepping up

Paul
