Once you purchase an original, one-of-a-kind artwork such as a card or painting, you are free to reproduce it but not for monetary gain and I should be credited as the artist.
On the other hand, I can reproduce artwork after it has been purchased and sell reproductions.
For instance, if you buy a card, I can still use the image on a magnet and sell it. However you cannot make and sell magnets. You may share the image and credit me as the artist.
If you wish to purchase artwork, commissioned or from my store to reproduce as in the case of an invitation or announcement, credit me as the artist. For instance, if I create a wedding or baby shower card, you can use the original to make invitations, magnets, posters or other keepsakes, but they cannot be sold and I should be given credit as the artist.
Any other questions, just send me a note.
