Hello,
 
 I have two ideas for greeting card lines but question their marketability.
 
1) Framable Cards: All occasion cards with no text on the front--only a"framable" fine art image.  
 
2) Coloring Book Cards: The pandemic caused may people to turn to crafts and adult coloring books for entertainment.  I design coloring book pages and wonder if they would be marketable on greeting cards.
 
What are your thoughts or experiences?
