She is selling these crosses here on her Etsy site. They are $10 each, and 100% of the money from these crosses goes directly to our adoption fund!!! If you see something else you like, be sure to mention "Adoption" and 100% will still go to the adoption fund. There is some other cool stuff on her site, including the tree she made me for my birthday.
Also, if you live near either my mom or me, you can buy a cross directly from either of us. She gave me a stash of them to have on hand. :)
