What's your next wallet design?
Well... What do you want?
I'll probably limit myself to about 1 or 2 new designs per year, especially until I find a more manageable way to deal with how the artwork bloats the GitHub zip file.
Maybe something fairly non-cultural, non-religious, e.g. "Happy Birthday"? Boring but I should probably be considering designs that apply to the most common gift-giving situations.
If you only want to do a couple of year, birthday + christmas. Christmas isn't religious any more, we celebrate it in Thailand and only about 1% of Thais are christian.
