Someone in my local area sells stuff like this. They contacted local groups - particularly mothers & toddlers and playgroups and asked to set up a stall at one end of the room. Did quite well out of it, too!
Try your local WI or offer them on sale or return to local department store, try a family owned one if you can find them. I work for a big company and we have a display of hand made cards in the staff restaurant, the young lady got in touch with HR. Good luck
I was going to say the same thing.. sell them on Ebay. Make sure you describe them as your own work, and if copyright exists, and a good clear pic will help with sales.
