Stephie, I hope you realize how many laws you are breaking right now. You cannot use trademarked or intellectual properties in your designs. Nessaholics and Walmart, amongst others, are both protected names. You cannot sell items with these names on them. EVEN IF proceeds go to charity.
I cannot make copies of BNN and sell them for charity.
It is the exact same thing. You must obtain the written permission of the person or persons who own the intellectual property.
Not the be a spoil sport, but you really need to do your research before you start trying to sell stuff like this. Consult a lawyer.
