I've created a new treasure card maker using the Magic Set Editor. This set is very customizable and is an improvement on the older treasure card maker I original posted.
There is an image slot for a picture of the treasure.
There are text fields for the name and description of the treasure. There are drop down fields for rarity and type of treasure, as well as attunement requirements. There are additional text fields for the weight and value of the treasure. And lastly, there are text fields for the illustrator and source for the treasure (in those cases that the description in rules were simply too long to provide in the space).
The style options allow for the attunement, value and weight to be hidden from the card, if you so desire, while keeping the data in your database for sorting and searching.
The style comes with 8 full color backgrounds and 20 textured backgrounds you can colorize. The style also enables you to choose the vibrancy of the textures and colors. The frame also comes in 8 choices. And there are 14 different font choices.
So, lots of options – you will find something in here that suits your style, and no two treasure card sets will be the same.
There is an edit function available to identify the fields on the card until you are used to the format.
Sample card are provided in the discussion thread.
Unfortunately, this download is NOT compatible with my older treasure card maker.
[Update 2017-04-17 -- Large Style added]
New style has been added to the download. The new large format prints treasure cards in 5" x 3.5" size, double the standard magic/treasure card size.
There are five different border/frame formats for your preference. You may add your own image of the treasure items and the image will cover the entire card, fading into the background behind the text or behind the frames. The stained glass frame is translucent, so images are seen through the glass frame.
The text box size is selectable, ranging from Large (75% of the card) to none (which provides only a treasure characteristics when there are no details needed or necessary). With the larger card size, more space is available for longer description if needed. Text auto scales as it is added to the text box.
